Problem: Let two objects of equal mass m collide. Object 1 has initial velocity v, directed to the right, and object 2 is initially stationary. Now suppose that the collision is perfectly inelastic. What are the velocities v1 and v2 of the two objects after collision?

FREE Expert Solution

The momentum of a moving object:

p=mv

Conservation of momentum:

m1v0,1 + m2v0,2 = m1vf,1 + m2vf,2

The objects stick and move together after the collision such that v1 = v2.
