A block of mass m = 2.00 kg slides down a 30.0° incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 7.20 kg which is at rest on a horizontal surface

Determine the speeds of the two blocks after the collision.
lighter block =
heavier block =

what would be the equation i would use?
