Question

During a baseball game, the pitcher throws the ball with a speed of
30 m/s The mass of the ball is 0 15 g What is the kinetic energy of
the ball when it leaves the hand?

Dear
Student,
As given the velocity, v = 30 m/s, and mass of the ball, m = 0 15 g
= 0 15 x 10-3Kg
We know the kinetic energy given by, K E
 = 12mv2        =12×0
15 ×10-3×30×30        = 67
5×10-3 J
