Question

A body of mass 9 kg moves in a (counterclockwise) circular path of radius 8 meters, making one revolution every 8 seconds. You may assume the circle is in the xy-plane, and so you may ignore the third component. A. Compute the centripetal force acting on the body.

Answer 1

centripetal Force
`=44.36\ \rm N`

Step-by-step explanation:

Given:

Mass of the body
`m=9\ \rm kg`

Radius of the circle
`R=8\ \rm m`

Time period
`T=8\ \rm s`

The centripetal Force acting on the body is given by F

`F=(4\pi^2 m R)/(T^2)\\F=(4\pi^2* 9*8)/(8^2)\\F=44.36\ \rm N`

Hence the centripetal force acting on the body is calculated
