Study Notes

Collision and Momentum

Final velocity of ball A after the collision is unknown and requires calculation
Change in momentum of ball A and ball B after the collision can be calculated using the law of conservation of momentum
Average force on ball B during the collision is related to the rate of change of momentum

Rocket and Armored Car Collision

Velocity of the combined masses just after the impact of the rocket and the armored car can be calculated using the law of conservation of momentum

Car Turning

Change in momentum of the car during the quick turn is related to the force exerted on the car and the time over which it is exerted
