1) A circular disk 0.20m in diameter starts from rest and accelerates with constant angular acceleration to an angular acceleration to an angular velocity of 210 rad/s in 10.00s. Find the angular acceleration and the angle which the disk has turned in degrees.

2) A car with tires of radius 32cm drives on the highway at 60km/h. What is the angular speed of the tires.
