Expert Answer Transcribed image text: A motorcyclist is traveling along a road and accelerates for 4.91 s to pass another cyclist. The police officer accelerates at a constant rate of 3 m/s^2 and maintains this rate of acceleration until he pulls next to the speeding car. A cyclist accelerates from rest. a) How much time does it take for the bike to com, A bicycle wheel of radius 0.70 m is rolling without slipping on a horizontal surface with an angular speed of 2.0 rev/s when the cyclist begins to uniformly apply the brakes. Do not round your answers. Then, the brakes are applied and the bike is brought to a uniform stop. What is the angular displacement of each wheel during this time? Then, the brakes are applied. In your computations, use the fact that 1 mile is equal to 5280 feet. During braking, the angular displacement of, A person is riding a bicycle, and its wheels have an angular velocity of 21.5 rad/s. What is the skater's acceleration?, A toy car accelerates from 3.0 m/s to a speed of 8.0 m/s, in 25 seconds. After turning through one-half of a revolution, the angular speed is reduced to 2.2 rad/s. What is his angular speed, in revolutions per hour?
