Two blocks are on a frictionless ramp. The first block has a mass of 5.00kg and is released from the top of the ramp 5.00m. It has a magnet on the front with the north pole facing out. The second block is at rest at the bottom of the ramp and has a mass of 10.00kg. The two blocks never touch. Calculate the maximum height block 1 rises back up the ramp after the collision.

2. Relevant equations

I assume I need to use m_{1}v_{1i}+m_{2}v_{2i}= m_{1}v_{1f}+m_{2}v_{2f}and the 1/2m_{1}v_{1i}^{2}.... equations. I'm having trouble with coming up with initial velocity for block 1 coming down the ramp.
