a. Through how many revolutions does a frisbee have to rotate to reach an angular speed of 570 rad/s if it starts from rest and experiences a constant angular acceleration of 160 rad/s2?

b. How long does it take the frisbee to reach the angular speed of 570 rad/s?

c. A cord is wrapped around a pulley of radius 33.0 cm and mass 4.00 kg. A tension of 15.0 N is applied to end of the cord. A friction torque of 1.5 N m opposes the motion. Find the net torque.
