Question

(10%) Problem S: You are told that a basketball player spins the ball on his finger with an angular acceleration of 101 rad s > 50% Part (a) What is the ball's final angular speed, in radians per second, if the ball starts from rest and the acceleration lasts 2.8 s?

Explanation / Answer

here ,

angular speed , a = 101 rad/s^2

part a) t = 2.8 s

final angular speed , w = a * t

w = 2.8 * 101

w = 282.8 rad/s

the final angular speed is 282.8 rad/s

part b)

the angular speed is very high , and the finger's can't rotate with this angular speed
