Part A - Practice Problem: In this example we will apply the equations for constant angular acceleration to the simple case of a rotating bicycle wheel. The angular velocity of the rear wheel of a stationary exercise bike is Wo = 4.00rad/s at time t=0, and its angular acceleration is constant and equal to a = 2.50rad/s". A particular spoke coincides with the + axis at time t=0 (Figure 1). What angle does this spoke make with the ads at...
