  1. May 10, 2009 #1
    1. The problem statement, all variables and given/known data
    The picture shows a body of mass 0.24kg attached to a fixed point P by a light string of length 0.80m. When the body is at A, vertically below P, it is given an horizontal velocity of 5m/s as shown. It the flollows a circular path to the position B. When it is at B, calculate:
    i) the velocity of the body
    ii) the centripetal acceleration of the body
    iii)the force exerted by the string on the body

    2. Relevant equations
    The chapter is "circular motion"

    3. The attempt at a solution
