A bicycle wheel is being tested at a repair shop. The angular velocity of the wheel is 4.00 [rad/s] at time t = 0, and its angular acceleration is constant and equal to -1.20 [rad/s]. A spoke OP on the wheel coincides with the +x-axis at time t = 0. 1. What is the wheel's angular velocity at t = 3.00 s? 2. What angle, in degree, does the spoke OP make with the +x-axis at this time?
