Find torque required so that a coin of mass `1kg` rotates `25` revolution in `5` sec starting from rest.

Calculate the force required to raise a car a velocity of 40 m/s in 10 sec starting from rest. The mass of the car is 1500 kg.

A sphere of mass 2 kg and radius 5 cm is rotating at the rate of 300 rpm. Calculate the torque required to stop it in 6.28 it in 6.28 revolution. Moment of inertia of the sphere about any diameter =2/5 MR^(2)

A coin is placed on the horizontal surface of a rotation disc. The distance of the coin from the axis is 1 m and coefficient of friction is 0.5. If the disc starts from rest and is given an angular acceleration (1)/(sqrt(2)) rad / sec^(2) , the number of revolutions through which the disc turns before the coin slips is
