The graph below shows the potential energy against displacement for a body of mass 80 g.

The body oscillates about point R. Calculate the velocity of the body at:
(i) P and T
(ii) Q and S
(iii) at R

Answers

(i) At P and T potential energy is a maximum and kinetic energy is a minimum. Hence
velocity is zero

(ii) At Q and S P.E has reduced by 0.1J. This equals the K.E


(iii) At R, auP.E has been converted to K.E velocity now is a maximum.

V=0.63m/s
