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 956.25 N.
This was found using the formula F = mv^2/r

Answer 2

Answer:

11.25 m/s^2

Explanation:

m = 85 kg, v = 15 m/s, r = 20 m

When an object is moving around a circular path, it exerts a force towards the centre of the circular path which is called centripetal force and the acceleration produced is called centripetal acceleration.

The formula for the centripetal acceleration is given by

a = v^2 / r = 15 x 15 / 20 = 11.25 m/s^2
