What should be his tilt angle so that he does not fall? (The angular speed = 30 rads/s. A bicycle wheel of radius 0.70 m is rolling without slipping on a horizontal surface with an angular speed of 14.44 rad/s when the cyclist begins to uniformly apply the brakes. All rights reserved. The angular acceleration of each wheel is +6.43 rad/s2 and, just after passing, the angular velocity of each is +82.8 rad/s, where the plus signs indicate counterclockwise directions. As he approaches a circular turn on the road he applies brakes and reduces his speed at a constant rate of 0.5 m/s^2.
