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
The chapter is "circular motion"
The Attempt at a Solution
I only need part i), i can manage the rest myself.
