Abowling ball with a mass of 7 kg rolls along a horizontal surface at 30 m/s.
what is its kinetic energy?

true is the correct answer

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
