Question

A 6x10-4 kg object is moving uniformly on a horizontal circular path of radius r = 6.3 m.

a. Find the period, T, the time for one rotation if its speed is 5x104 m/s.

b. Calculate its centripetal force.

Definition Definition Force on a body along the radial direction. Centripetal force is responsible for the circular motion of a body. The magnitude of centripetal force is given by F C = m v 2 r m = mass of the body in the circular motion v = tangential velocity of the body r = radius of the circular path
