Question

A ball with a mass of 0.25 kilogram is swung on the end of a rope that is 3.0 meters long. The ball travels with a linear velocity of 10.00 meters per second. What centripetal force is acting on the ball?

Answer 1

I assume "linear velocity" means tangential velocity.

F=mv²/r
=0.25(10²)/3
=25/3 N
