- A person is riding a bicycle, and its wheels have an angular velocity of 16.1 rad/s. Then, the brakes are applied and the bike is brought to a uniform stop. During braking, the angular displacement of each wheel is 12.7 revolutions. (a) How much time does it take for the bike to come to rest? (b) What is the anguar acceleration (in rad/s2) of each wheel?Peg P is driven by the fork link OA along the curved path described by r 2.8.8 ft. At the instant = 1.3 rad, the angular velocity of the link is = 1.4 rad/s and the angular acceleration is 0=0.66 rad/s². For peg P at this instant, please find: radial acceleration a, a -10.55 transverse acceleration ag= magnitude of total acceleration a= m m m 5²A motorcycle, which has an initial linear speed of 6.6 m/s,decelerates to a speed of 2.1 m/s in 5.0 s. Each wheel has a radius of 0.65 mand is rotating in a counterclockwise (positive) direction. What are (a) theconstant angular acceleration (in rad/s2) and (b) the angular displacement (inrad) of each wheel?
