Question

A wheel rotates without friction about a stationary horizontal axis at the center of the wheel.A constant tangential force of 75N is applied to the rim of the wheel.The wheel has a radius of 0.13m.The wheel has an angular speed of 14.5rev/s after 3.70s.What is the momentum of inertia of the wheel if it's starting from rest?

moment= torqe/angular scceleartion

Torque=75*.13 N-m
angular acceleration= 14.5*2PI/3.7 rad/sec
