A bicycle wheel of radius 0.50 m is rolling without slipping on a horizontal surface with an angular speed of 3pie rad/s when the cyclist begins to uniformly apply the breaks. The bicycle stops in 4.0 s.
1. what is the angular deceleartion in radians second squared of the bicycle wheel?
2. What is the linear deceleration of the bicycle in m/s2
3. What is the initial tangential velocity of the bicycle wheel?
4. What angular displacement did the bicycle wheel rotate during the 4.0 seconds of braking?
5. How far did the bicycle travel during the 4.0 seconds of breaking?
A dad pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 16 rpm in 11.5s . Assume the merry-go-round is a uniform disk of radius 2.5m and has a mass of 800 kg , and two children (each..
