Question

four different balls are moving at the same velocity. which will have the greatest kinetic energy as it rolls? a golf ball a bowling ball a tennis ball a soccer ball

Explanation:

Step1: Recall kinetic - energy formula

The formula for kinetic energy is $K = \frac{1}{2}mv^{2}$, where $m$ is mass and $v$ is velocity.

Step2: Compare masses

Since the velocity $v$ is the same for all balls, the ball with the greatest mass $m$ will have the greatest kinetic energy. Among a golf ball, a bowling ball, a tennis ball, and a soccer ball, a bowling ball has the greatest mass.

Answer:

B. a bowling ball
