(A) If its angular acceleration is constant and equal to 0.200 rad/s^2, what is its angular velocity at t = 2.30 s? How fast will a point on the rim of the tire (diameter = 68 cm) at the top be moving after 2.4 s? {/eq}. The driver steps on the accelerator, and in a time of 14.2 s the angular velocity increases to +263 rad/s. A motorcyclist is traveling along a road and accelerates for 6.24 s to pass another cyclist. a. What is the magnitude of the cyclist's acceleration? \\ What is the angular acceleration of the whee, A bicyclist starting at rest produces a constant angular acceleration of 1.60 rad / s^2 for wheels that are 38.0 cm in radius.
