The pciture shows a body of mass .24kg attached to a fixed point P by a light string of length .8m. When the body is at A, vertically below P, it is given an initial hosirontal velocity of 5m/s as shown. It then follows a circular path to the point B. When it is at B calculate:
i) The velocity of body
ii) The centripetal acceleration of the body
iii) The force exerted by the string on the body.
