circular motion

Question

 A bicycle wheel has a radius r = 0.24 m and rotates at a constant frequency of f = 59 rev/min.

a) calculate the period of rotation of the wheel in T seconds

b) what is the tangential speed of a point on the wheels outer edge in m/s?

Answer 1

frequency = f=59 rev/min ... Period =T=1/f = 1.017 seconds a)

w=59/2π radians/minute = 59/2π/60 = .157 rad/sec ... tangential velocity = wr = .157*.24/2= .0188 m/s
