A baseball player is working on throwing velocity and accuracy with his coach?

Question

His first throw is clocked at 80 Km/hr and each succesive throw increases in velocity by 1.5% of the previous throw . He throws a ball 40 time in total
I know that the velocity of the baseball player can be determind by using the geometric sequence t=ar^n-1, but I don't know how to find out about rhe common ratio r
I calculated the ratio 3/2 but I am not sure is my answer is correct or not?

Answer 1

V2 = V1 + 0.015v1 = v1(1.015)
therefore r = 1.015, and
Vn = 80*1.015^39

Answer 2

Throw 1 is 80 kph and each succesive throw goes up by a factor of 1.015 so the 40th throw is 1.015^39 faster than 80kph

exp(log(1.015)*39) is 1.7872 on my calculator so I think your ratio is too low (but I could be completely wrong).

Answer 3

Pin factor accuracy is almost unparalleled. i might say the main crucial situation is to maintain the hitters off stability. this is lead them to difficulty regardless of if the subsequent pitch is "smoke of their ear" or a "hook low and away." on the optimum ranges of the interest the main crucial situation is to have greater suitable than one pitch you may throw on any count quantity. As a youthful participant i might say that the main crucial situation is conserving it interior the strike zone and in maximum circumstances down. If the pitch is going to be greater suitable enable the batter do it. in case you do no longer throw strikes they're going to wait you out.
