Question

A particle complete 4 revolution per second on a circular track of radius 0.25 m calculate the angular velocity and centripetal acceleration of particle

Answer 1

Answer:

Frequancy=4

r=0.25m

angle subtended by body in 4 revolutions

theta=4×2pi=8pi rad

angular velocity=theta/t=8pi×frequancy

angular velocity=32pirad/s

centripetal accalration=(angular velocity)^2×radius

centripetal accalration=(32×22/7)^2×0.25
