1. The problem statement, all variables and given/known data

Block 1 of mass m1 slides from rest along a frictionless ramp from height h = 3.10 m and then collides with stationary block 2, which has mass m2 = 5.00m1. After the collision, block 2 slides into a region where the coefficient of kinetic friction μk is 0.550 and comes to a stop in distance d within that region.What is the value of distance d if the collision is (a) elastic and (b) completely inelastic?

2. Relevant equations

I know M1U1+M2U2=M1V1+M2V2 when it is elastic.

3. The attempt at a solution

So using that equation, i found V2=3.5m/s. But then i have no idea how to find the distance... Help anyone??
