A person is riding a bicycle, and its wheels have an angular velocity of 10.6 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 10.6 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?
a 100g marble (modeled as a solid sphere with radius 2cm) rolls without slipping down a ramp. How tall is the ramp
