Consider a basketball player spinning a ball on the tip of a finger. If a player performs 2.01J of work to set the ball spinning from rest, at what angular speed ω will the ball rotate? Model a basketball as a thin-walled hollow sphere. For a men's basketball, the ball has a circumference of 0.749 m and a mass of 0.624 kg.

The angular speed of ball is 25.9 rad/s .

Explanation:

Given :

Work done by the player , W = 2.01 J .

Mass of hollow spherical ball , m = 0.624 kg .

Circumference of hollow spherical ball , C = 0.749 m .

Therefore , its radius is ,

Now , this work done must be equal to the rotational energy of the ball .

We know ,

Therefore ,

Hence , this is the required solution .

i was thinking more like reflects green light, just not sure

none, its a machine
