A grinding wheel is in the form of a uniform solid disk of radius7.00 cm and mass 2.00 kg. It starts from rest and acceleratesuniformly under the action of the constant torque of 0.600 Nm thatthe motor exerts on the wheel. (a) How long does the wheel take toreach its final operating speed of 1 200 rev/min?
2. A disk 8.00 cm in radius rotates at a constant rate of 1 200rev/min about its central axis. Determine the tangential speed at apoint 3.00 cm from its center.
3.A wheel starts from rest and rotates with constant angularacceleration to reach an angular speed of 12.0 rad/s in 3.00 s.Find the angle through which it rotates in this time .
