approaches a heavy rectangular box at a speed of 
and rebounds at a speed of 
as shown below.
is moving with a velocity 
. If a force of 
acts on the ball and its speed increases to 
, calculate the period of time for which the force act on the object.
is moving at a speed of 
. A force then acts on the object and it begins to move at a speed of 
. What is the change in momentum of the object?
falls vertically downwards to the floor. If the speed of the ball, just before it hits the floor, is 
and it rebounds from the floor with a speed of 
, what is its change in momentum?
downwards

. While still in motion, a bag weighing 6 kg is placed on it. What is the speed of the cart after the bag was placed?
. The mass of the second wagon together with the load is 2000 kg and its speed is 
. The two wagons collide and stick together. They move forward at a speed of v along the railway track. Determines the speed and direction of both wagons after the collision.
crashes at a speed of 72 
into a wall and comes to rest. The collision lasts 
. At what deceleration does the car stop?
. The arrow then crashes into a wooden board, which brings it to rest in 
. How much force does the board apply to the arrow to stop it?
is moving towards the East at a speed of 
. A second ball of mass 
is stationary. The first ball strikes the second ball. If the second ball moves towards the East at a speed of 
, what is the speed of the first ball after the collision?
is moving at a speed of 
in a straight line. What is the momentum of the body?
traveling at a speed of 
collides with another body of mass 
traveling at a speed of 
in the same direction. What is their speed if the two bodies stick and travel together after collision?
accelerates from a velocity of 
to a velocity of 
. What is the force impulse that causes this acceleration?
resting on a frictionless, horizontal surface is struck by a bullet of mass 
traveling horizontally at a speed of 
. If the bullet is stuck in the block, what is the common velocity of the block and the bullet after the impact?
traveling at a speed of 
strikes a stationary wooden box of mass 
as shown below.
