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:
$\frac{mv^2}{r}$
After substituting the values from the question into the equation, we get:
$\frac{85*15^2}{20}$
This solves to give a value of 956.25N
