1) Two arrows mass 0.1kg each are shot horizontally with the same speed of 30ms^-1, one from east and the other from south meeting at a point. Find the magnitude and direction of the total momentum of both arrows.
2) two cars A & B are moving in the same direction along a straight line. Car A has 4 times the momentum and twice the kinetic energy of B.
a) determine the ratio of mass A to B.
b) the ratio of the velocity of A to B is?
