Homework Help: Physics

Posted by charlie on Tuesday, June 16, 2009 at 1:05pm.

In an elastic collision:

mass a is 1kg, and is moving at 100ms^1 in the +ve x direction when it hits mass b, 10kgs at rest. Given: mass a moves off at 80 ms^1 in the -ve x direction. What's the final velocity of mass b.

Using cons of momentum, i say 2 ms^1 in the +ve x directon. Is that correct.

Thanks.
