Question

An 85 kg object is moving at a constant speed of 15 m/s in a circular path, which has a radius of 20 meters. What centripetal force is exerted on the body?

Answer 1

The centripetal force is equal to:

`(mv^2)/(r)`
After substituting the values from the question into the equation, we get:

`(85*15^2)/(20)`
This solves to give a value of 956.25N
