A cyclist starts from rest and pedals such that the wheels of his bike have a constant angular acceleration. After 18.0 s, the wheels have made 190 rev. What is the angular acceleration of the wheels?

Question

What is the angular velocity of the wheels after 18.0 s?

If the radius of the wheel is 34.0 cm, and the wheel rolls without slipping, how far has the cyclist traveled in 18.0 s?

Answer 1

use 1/2alphat^2=2pi*revolutions to find alpha then use wf=wi+alpha(t) to find the final angular velocity
