Momentum Quiz 2 (Conservation of Momentum)

A 10kg box is moving at 3m/s to the right towards a 20kg box initially at rest. What is the total momentum of the system before the collision? What would be the total momentum of the system after the collision? All work/explanations must be shown. A picture must be attached to receive credit.

A 10kg box is moving at 3m/s to the right towards a 20kg box initially at rest. What would be the velocity of the 10kg block if the collision was perfectly inelastic? All work/explanations must be shown. A picture must be attached to receive credit.

A 10kg box is moving at 3m/s to the right towards a 20kg box initially at rest. What would be the velocity of the 20kg block if the 10kg block bounced back at a speed of 2m/s after the collision? All work/explanations must be shown. A picture must be attached to receive credit.

Two objects, one of mass 5kg and one of mass 7kg, are held together at rest with a compressed spring between them. Once released the masses push away from each other. What would the velocity of the 5kg object be if the 7kg object was measured to have a velocity of 1m/s? All work/explanations must be shown. A picture must be attached to receive credit.

A 100kg box and a 50kg box are moving towards each other. The 100kg box is measured to have a velocity of 3m/s. What velocity would the 50kg box need to have in order to make the boxes stop moving after colliding and sticking? All work/explanations must be shown. A picture must be attached to receive credit.
