Speed
Hello everybody its Bobbybhai. I had a quick question from 22 yards like if somebody throws the ball how many seconds from the ball to the bat would be 80 miles per hour?

Ok I will be kind to you
80 mile/hour = 0.022 222 222 mile/second i.e 2.67 seconds |

That can't be right! 2.67 secs is a long time when you're out there in the middle. Akhtar's delivery (around 90mph) takes less than half a second.

Come on man, 22 yards is roughly 19.8m. This is 0.012 miles. Time therefore is 0.54 seconds.

1. 22 yards = 20.1168metres /1600metres = 0.0138miles 2. Reaction Time = distance/speed = 0.0138miles/80mph = 0.0001725hours * 3600secs = 0.621secs |

Take into note the approx 20% slow down that a ball experiences due to air resistance and when it hits the pitch. Sadly this slow down isnt linear and would be pretty hard to factor in

80 Miles Per Hour!!!
Hey guys my name is Jibran and i just turned 15 and i think i bowl pretty fast. Whenever i bowl everybody thinks i bowl pretty fast. I think i bowl 80 miles per hour because thats what alot of people say. How was fast it it exactly from when you release the ball till when it hits the bat is 80 Miles hour. Please let me know thanks!

not sure what you are asking but in cricket the speed is measured at the time ball is released. it may lose over 10 mph by the time it reaches the batsman.

I seriously doubt u'll be bowling at 80mph coz ur mates would find it pretty difficult to face u at that speed. If they're ok with u bowling at them speeds then rush them off to Pakistan and get em in the national team.

good luck if you really are that fast!

Its fast for club. maybe first class. you have a chance but you have to be overall good cricketer.

Afridi can also bowl 80 mph. 80 is nothing, if you don't know how to bowl.

Thanks guys for you trips but i'm going to go to Pakistan next year in the summer. Also after i am done with studies my goal is to make the Pakistan Team that's my dream. I think if i bowl really fast in Club Cricket i will make the Karachi team then do good there and make the national Team.

It is highly unlikely that at 15 you will be bowling at that speed. If you do not have access to a speed gun, go to a first Class ground and offer to bowl in the nets at batsmen who are used to facing bowlers in the range 50 - 85 mph. They would be able to give you a feel for what speed you are likely to be bowling. If you are seriously fast, you need to be a t a club or academy where your action and the amount you bowl is monitored carefully. At 15 bowling 70 - 80 mph is putting a serious amount of stress on bones that are still growing. Take care of yourself. |

Hahah, this is my little brother. And he's playing with you guys. I myself am around 70 mph and he's a good 10 miles slower than me. Still young though, only about to be 16.

First, i hope that you are telling the truth. Because this is not the forum where we expect from people to lie. If i take you at face value that by the time your ball reaches the batsman it is 80 mph then i think you are a fast bowler. You have to understand the pitch is about 22 yards and by the time bowl reaches the batsman it lose its speed. It is simple physics. That means you must be clocking at least 90+ mph in order for your ball to be at 80mph by the time it reaches other end. Again there are always factors which work in this regard. But if you the speedgun can prove that i think you are a pretty fast.

My mate who is 14 has been clocked at 120kph at an indoor cricket centre. So this lad here could be telling the truth.

One of my friends Usman Shuja had been playing in the US national team and he is considered to be one of the fastest if not the fastest bowler in the US. I've seen him bowl and also played his deliveries and he sure was pretty damn fast. He attended the Pepsi bowling speed competition (the same one where this kid Talha bowled at 86mph) a year back and turned out his speed was 79mph.
http://www.squarelegsports.com/team_squareleg.htm So I think its highly unlikely you're bowling 80mph especially at age 15. If you are then well you have a rare talent and could turn out to be a speed demon like Zahid. Last edited by lahori; 9th June 2007 at 06:43. |

Zahid. Mohammad Zahid. The bolwer who was considered to be as fast if not faster than Shoaib before injury broke his career down.

I remeber watching it showing how fast it comes out of the hand until it reaches the batsman and it was around 10kph slower when lee bowled it to the batsman.

1 mile = 1760 yards
1 yards = 0.000568181818 miles 22 yards = 0.0125 miles = 1/80 miles In a vacuum it would take (60 x 60 ) / (80 x 80) = 0.5625 seconds Air pressure generally is higher the faster the object is. So deceleration = M x speed which in this case = 80* M (in miles) M being a constant depending on air pressure on the day After bouncing the speed of the ball changes. The resulting speed depends on the surface of the pitch and the momentum of the ball at the time it hits the ground. As momentum = velocity x mass and mass of the ball is generally the same we will say that the resulting speed is N. So depending on where the bowler decides to bounce the ball. Taking the bounce of the ball to be from the bowlers crease = D Taking the following Than the total time taken for the ball to cross the 22 yards is Without taking deceleration into account the time taken for the ball to reach the 22 yard mark after bouncing = ( 22 -d)/N t = BEFORE BOUNCE + AFTER BOUNCE BEFORE BOUNCE = 80 mph + 80^2mph + 2 * 80M * D AFTER BOUNCE = N + N^2 + 2MN * (22-D) Hope that answers the question. Note that D and 22 are in yards and the speed is in MPH and we have also not taken into account the vertical velocity as it depends on the height of the bowler and whatever the case it will be negligent.

First, the point of release to the point of impact on the bat is probably a distance of 20 not 22 yards , as both the bowler and the batsman aren't stood at the stumps and 22 yards is stump to stump distance. Secondly on most surfaces a ball loses around 10% of its velocity on impact. A good length ball can be assumed to have travelled 18 yards before bouncing and therefore travels around 2 yards after it. It is not unreasonable to assume standard air pressure at sea level. Your table then to help the young lad should give the sensitivity of your answer of time elapsed based on standard sea level pressure, 10% loss of velocity on impact, 20 yard travel with 18 pre bounce, to the main variables you have identified that would significantly affect the time elapsed ie air pressure and loss of momentum on impact. Unfortunately the biggest variable in practical measurement is likely to be the measurement of elapsed time using a hand held stop watch - but this could be overcome by taking a video of the bowling with a big stopwatch in the background that records 100ths of a second. I look forward to seeing your table posted in the near future. |

I know a person who is a lightning quick fast bowler and you literally cannot see his bowl as a batsman, until the last moment. A few professional coaches I talked with reckon hes about 85+mph. Hes also 19 and really built like a fast bowler. Still work with your coach or friends and remember all the different variables as Wazeeri pointed out. You might reach there.

then use the friction method you described somewhere where you may have called it D but the standard is F. F = city * temp / Mali where city is from where did the soild came from (values in ICC tables) and Mali is the groundsman rating also in ICC table |

My buddy bowls fairly quick. well, quick enough to keep most of the guys on their toes, except when he clocked himself he was barely touching 73~75mph range.
btw, he is 21, so i my doubts with you bowling @ 80mph. In anycase good luck, there was a 16 year old somewhere from karachi when pepsi did the speed challenge, he was doing what 86mph? so its clearly possible.

Mark Footit for Notts was clocked at 80mph when he was 15, I faced him a few times when he played for papplewick in the Notts league and he was rapid! He bowled a bouncer to my mate cracked him on the helmet and snapped the peak of it in half, and that was an U15 game!
