A0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. the
velocity of the rock is 4.50 m/s. what is the centripetal force acting on the rock?
5.22 n
23.5 n
69.8 n
15.5 n

23.5 N

We are given;

We are required to calculate the centrifugal force.

First, we need to know what is centripetal force.

Second we need to know how it is calculated.

Third, we answer our question.

Thus, the centripetal force acting on the rock is 23.5 Newtons
