Question

s) A body of mass 2 kilograms moves on a circle of radius 3 meters, making one revolution every 5 seconds. Find the magnitude of the centripetal force acting on the body. (Be sure to correctly state the units of the force

Answer 1

Centripetal force acting on the body = 9.47 N

Step-by-step explanation:

Mass of body, m = 2 kg

Radius, r = 3 m

It makes one revolution in 5 seconds.

Period, T = 5 s

`\texttt{Angular velocity, }\omega =(2\pi )/(T)=(2\pi )/(5)=1.256rad/s`

Centripetal force, F = mrω²

F = 2 x 3 x 1.256² = 9.47 N

Centripetal force acting on the body = 9.47 N
