Question

A body of mass 10kg revolves in a circle of diameter 0.04 m,making 1000 revolution per minute. calculate linear velocity and centripetal force​

Answer 1

Answer:

Linear Velocity = angular Velocity x Radius of rotation

Omega = 2× Pix1000÷60 = 6280/60= 104.67

R= 0.04

V = 4.19 m sec^-1

F = M v^2/R = 10x 4.19^2/0.04

F centripetal= 4382 Newton
