Question

0.63 kg ball leaves the player's hand at 12 m/s. What is the kinetic energy of the ball during the play?

A. 45.36 joules
B. 63.42 joules
C. 81.48 joules
D. 100 joules

Answer 1

The kinetic energy of the ball during play is 45.36 joules.

Step-by-step explanation:

The kinetic energy of an object can be calculated using the formula:

Kinetic Energy = 0.5 * mass * velocity^2

In this case, the mass of the ball is 0.63 kg and the velocity is 12 m/s. Substituting these values into the formula, we get:

Kinetic Energy = 0.5 * 0.63 kg * (12 m/s)^2 = 45.36 joules

Therefore, the kinetic energy of the ball during play is 45.36 joules.
