Problem
A mass of 300g attached to the end of a light string is made to travel in a circular path of radius 1.2m by a centripetal force of 4N.
(a) Calculate the distance travelled by the mass in one complete circle.
(b) State the work done on the mass by the centripetal force during one complete circle. Explain your answer.
