Question
A cyclist starts from rest and pedals such that thewheels of his bike have a constant angular acceleration. After 18.0s, the wheels have made 167 rev. a. What is the angular acceleration of thewheels? b. What is the angular velocityof the wheels after 18.0 s? c. If the radius of the wheel is37.0 cm, and the wheel rolls without slipping, how far has thecyclist traveled in 18.0 s? a. What is the angular acceleration of thewheels? b. What is the angular velocityof the wheels after 18.0 s? c. If the radius of the wheel is37.0 cm, and the wheel rolls without slipping, how far has thecyclist traveled in 18.0 s?Explanation / Answer
a)the angular acceleration is given by 2/2*angular distance is obtained from part b b)final angular velocity= angular distance =average angular velocity*time average angular velocity is /2 hence we have *18/2=167rev hence =18.55rev/sec c)v=r and distance traveled is v*t/2
