Question

A flywheel stars from rest It attains an angular speed of 100
rev/s in 5 seconds under uniform angular acceleration what is the
net angular acceleration and the angle by which it rotates during 5
seconds?

Jyoti Pant · Accepted Answer

Given,
Angular speed=100 rev/s
=100×2π rad/s=200π rad/sAngular acceleration in 5 seconds,200π5=40π rad/s2=125
6 rad/s2Angle or angular displacementθ=ω0t+12at2=0+12×40π×25=500 π rad

A flywheel stars from rest. It attains an angular speed of 100 rev/s in 5 seconds under uniform angular acceleration. what is the net angular acceleration and the angle by which it rotates during 5 seconds?
