(Figure 1) shows the angular position of a potter's wheel.
Part A What is the angular displacement of the wheel between t = 5 s and t = 15 s? Express your answer in radians.
Part B What is the angular velocity of the wheel at 15 s? Express your answer in radians per second.
Part C What is the maximum speed of a point on the outside of the wheel 15 cm from the axle? Express
