How do you set this up?

**bobpursley**, Tuesday, August 9, 2011 at 10:20pmtwo equations: Conservation of momentum

M1V1+m2(0)=M1V1' + m2V2'

solve for v2' in terms of all others.

second equation: conservation of energy

M1V1^2+0=M1V1'^2 + m2V2'^2

put the v2' equation into that equation, and solve for v1'

A bit of algebra is required, get a pad of paper.

- Dont get it? -
