1.	A light mass and a heavy mass have equal momentum. Which will have more kinetic energy?(Hint : Kinetic energy K = P2/2m where P is the momentum)
Answer» Kinetic energy, k = p²/2m where p is the momentum. Both the masses have same momentum p. The kinetic energy, K is inversely proportional to mass of the body. Hence light mass body has more kinetic energy because smaller the mass, larger is the kinetic energy.

Answer»

Kinetic energy, k = p²/2m where p is the momentum.

Both the masses have same momentum p. The kinetic energy, K is inversely proportional to mass of the body.

Hence light mass body has more kinetic energy because smaller the mass, larger is the kinetic energy.
