Consider a frictionless track as shown in the diagram below. A block of mass m1=8.00kg is released from point A at a height of 5.00m. It collides with a block of mass m2=10.0 kg, initially at rest, at point B. The two blocks stick together. Determine the final velocity of the blocks Relevant equations M1V1+M2V2 = (M1+M2)(Vi) [1/2(MVf^2)-1/2(MVi^2) + (MGHf - MGHi) I havent attempted this problem, I wanted to make sure that it was the second equation and If I am right I think I should just plug into the second equation and solve for Vf.
