Cyclist!
A cyclist starts from rest and pedals such that the wheels of his bike have a constant angular acceleration. After 14 s, the wheels have made 40 rev.
What is the angular velocity of the wheels after 14 s in rad/s ?
Given the angular displacement and the time, you can calculate average angular velocity. Then, final angular velocity. Remember to convert angular velocity(omega) to units of rad/s
2*Pi rad = 1 revolution.
What is the angular acceleration of the wheels in rad/s^2 ?
If the radius of the wheel is 30 cm, and the wheel rolls without slipping, how far has the cyclist (in m) traveled in 14 s?
