A bicycle with tires 68 cm in diameter travels 7.2 km in 20.0 minutes.

Question

If the bicycle maintains a constant translational speed, what is the angular velocity of each wheel?

Answer 1

Given:

d = 0.68 m

r = 0.34 m

X = 7200 m

t = 20 min* 60 sec/min = 1200 sec

Find: 

w =?

Solution:

V = 7200/1200 = 6 m/sec

V = w*r

w = V/r = 6/0.34 = 17.6 rad/sec
