The grinding wheel is in the form of the uniform solid disk of radius 7.00 cm and mass 2.00 kg. It begins from rest and accelerates uniformly beneath the action of the constant torque of 0.600 N * m which the motor applies on the wheel.
i) Determine how long does the wheel take to reach the final operating speed of 1,200 rev/min?
ii) From how many revolutions does it turn while accelerating?
