A mass, m₁ = 3kg is initially travelling with a speed of 4 m/s, and runs into a mass m², that is initially at rest. After the collision, the mass m₁, has reversed direction, and is travelling at 2m/s.   a. What is the magnitude of the momentum of mass m₂ after the collision? b. For this part, assume mass m₂ =9kg. Is this an elastic or inelastic collision? Provide a written and mathematical argument to justify your answer.

A bullet is fired into a block of wood sitting on a block of ice. The bullet has an initial velocity of 500m/s and a mass of 0.005kg. The wooden block has a mass of 1.2kg and is initially at rest.

An object has a mass of 2kg moving to the right with velocity of 12m/s and collides head on with a stationary object whose mass is 6kg. The collision is perfect elastic so what is the final velocity of the 2kg object and if the final velocity of 6kg object is 6m/s to the right? How do i solve and use the formulas in the pic
