Q.1.
What is the momentum of an object which has a mass of 5 kg travelling at a speed of 2.5 m/s?
Q.2.
A 0.5 kg trolley is pushed at a velocity of 1.2 m/s into a stationary trolley of mass 1.5 kg. The two trolleys stick to each other after the impact. Calculate the velocity of the two trolleys straight after the impact assuming a closed system.
Q.3.
A 0.5 kg trolley is pushed at a velocity of 1.2 m/s into a stationary trolley of mass 1.5 kg. The two trolleys stick to each other after the impact. Calculate the momentum of the 0.5 kg trolley before the collision.
Q.4.
An object of mass 1000 kg moving at a velocity of 5 m/s on a level surface, collides with, and becomes attached to, a stationary object of mass 1500 kg. Calculate the velocity of the two moving objects after the collision.
Q.5.
A car and a truck are both travelling along a motorway at 30 m/s and 20 m/s respectively. The car has a mass of 1,200 kg and the truck has a mass of 4,500 kg. Which one requires the greater force to stop?
Q.6.
An object of mass 1000 kg moving at a velocity of 5 m/s on a level surface, collides with a stationary object of mass 1500 kg. Calculate the momentum of the 1000 kg object before the collision.
