Your 64-cm-diameter car tire is rotating at 3.0 rev/s when suddenly you press down hard on the accelerator. After traveling 170 m, the tire's rotation has increased to 5.5 rev/s. What was the tire's angular acceleration? Give your answer in rad /s2. Express your answer with the appropriate units. IVO AEQ a rad/$2A wheel initially rotating at 62 rpm experiences the angular acceleration shown in (Figure 1). What is the wheel's angular velocity, in rpm, at t = 3.0 s?
