Answer to Question #168643 in Physics for Hana

Question

A body of mass 100kg moves at a constant speed of 20 rad / s per circle with a radius of 20cm. How much centripetal force acts on the body?

Answer 1

$F=ma=m\frac{v^2}{R}=m\frac{(\omega R)^2}{R}=m\omega^2R=$

$=100\cdot20^2\cdot0.2=8000\ (N)$ .Answer
