http://answers.yahoo.com/question/index?qid=20130517183728AARifZr

I really want to understand this...
There are two objects which will collide (Inelastic collision), both initial velocities are initially zero. Object 1 will start at this initial velocity of 0, increase velocity and collide with Object 2 and yield the a certain energy.

I have the masses of both objects 1 and 2.
I know that the initial velocities for both are 0.
I have the final energy of the system after the collision occurs.

How do I find the FINAL velocity of mass 1? Please just explain how.

Explanation / Answer

u can calculate using formula

m1u1 + m2u2 = m1 v1 + m2v2

u1 , u2 are initial velocities and v1 and v2 are final velocities
