# WORKED EXAMPLES

#### EASY

##### Body A of mass 5.0 kg moves to the right with a velocity of 4.0 m s^{-¹}. Body B of mass 3.0 kg moves to the left with a velocity of 8.0 m s^{-¹}. Calculate (a) the momentum of A, (b) the momentum of B, (c) the total momentum of A and B.

##### Answer

#### MEDIUM

##### A projectile of mass *m* is fired with initial velocity *u* from a point P as shown below. The projectile lands with velocity *v* at angle *θ* to the ground.

##### Neglecting air resistance, in terms of *m, v*, and *θ*, determine the magnitude of the change in momentum of the mass between leaving P and entering Q is

##### Answer

#### HARD

##### A 200 g billiard ball rebounds off the wall with velocities as shown in the diagram. Evaluate the change in momentum of the ball.
