Which situation describes an inelastic collision?

A 5.0-kg meatball is moving with a speed of 7.0 m/s directly toward a 2.0 kg meatball which is at rest. The two meatballs collide and stick together. What is their velocity immediately after the (inelastic) collision?

A 13,500 kg railroad freight car travels on a level track at a speed of 2.5 m/s. It collides and couples with a 15,000 kg second car, initially at rest and with brakes released. What is the speed of the two cars after collision?

A 50 kg girl skates at 2.5 m/s on an ice rink toward her 75 kg friend who is standing still, with open arms. As they collide and hold each other, what is the speed of the couple?

3

Two objects, A and B, with masses of 3.2 kg and 1.8 kg, move on a frictionless horizontal surface. Object A moves to the right at a constant speed of 5.1 m/swhile object B is stationary. They collide and stick together (a perfectly inelastic collision). What is these blocks' final velocity?

A 2400 kg car traveling at 36 m/s collides with a 3200 kg car that is at rest. The two bumpers lock and the cars move forward together. What is their final velocity?

A bullet with a mass of 0.020 kg collides inelastically with a wooden block of mass 2.5 kg, initially at rest. After the collision, the bullet + block has a speed of 0.6 m/s. What was the initial speed of the bullet?
