physics problem angular acceleration?

Question

a ferris wheel rotates at an angular velocity of 0.24 rad/s. starting from rest, it reaches its operating speed with an average angular acceleration of 0.030 rad/s^2. how long does it take the wheel to come up to operating speed?

Answer 1

It takes eight seconds to reach the operating angular speed of 0.24 rad/s. Simply divide the angular velocity by the average angular acceleration to determine the time.
