A wheel of mass m = 16kg and radius r = 0:5m is connected to a motor that causes it to attain rotational speed of w = 20rads^-1 in 10s, starting from rest.
(a) Treating the wheel as a solid disk, calculate its rotational inertia.
(b) What is the average torque applied to the wheel by the motor?
(c) If this wheel then comes in contact with a at road and starts rolling (without slipping) what is its translational kinetic energy?
