1- 1. A motor's shaft is spinning at a speed of 3000 r/min. What is the shaft speed in radians per second?
1- 2. A flywheel with a moment of inertia of 2 kg 0 m2 is initially at rest. If a torque of 5 N o m (cOlUlterc1ockwise) is suddenly applied to the flywheel, what will be the speed of the flywheel after 5 s? Express that speed in both radians per second and revolutions per minute.
1-3. A force of 10 N is applied to a cylinder, as shown in Figure PI- I. What are the magnitude and direction of the torque produced on the cylinder? What is the angular acceleration a of the cylinder?
