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

Answer 1

The bowling ball, having the greatest mass among the four types of balls mentioned and moving at the same velocity, will have the greatest kinetic energy.

Step-by-step explanation:

The kinetic energy (KE) of an object is given by the formula KE = ½mv², where m is the mass of the object and v is its velocity. Since all four balls are moving at the same velocity, the ball with the greatest mass will have the greatest kinetic energy. Looking at the given options: a golf ball, a bowling ball, a tennis ball, and a soccer ball, a bowling ball typically has the greatest mass. Therefore, the bowling ball will have the greatest kinetic energy as it rolls, provided that they are all rolling at the same velocity.

Answer 2

If four balls were moving at the same velocity, I believe Option B) A bowling ball would have the greatest kinetic energy as it rolls. Kinetic energy increases when the mass increases, and since the bowling ball from all these options has the greater mass, then it mean's the bowling ball would have the highest kinetic energy.

I hope this helps!
