1) A 10.0 g moving to the right at 20.0 cm/s makes and elastic head on collision with a 15.0 g object moving in the opposite direction at 30.0 cm/s. Find the velocity of each object after collision.
2) a 90 kg fullback moving east with a speed of 5 m/s is tackled by a 95 kg opponent running north at
3.0 m/s. If the collision is perfectly inelastic, calculate
a) the velocity of the players just after the tackle
b) the kinetic energy lost as a result of the collision
