8) Two bodies of masses have the same linear momentum. What is the ratio of

their kinetic energies?
9) Draw a graph of spring force F s and displacement x. Hence derive an expression for

potential energy of an elastic stretched spring.

10) Derive an expression for kinetic energy of a body of mass m moving with a velocity v.
