A small block of mass 0.5 kg is released from rest at the top of a ramp of mass 3 kg that sits on a frictionless horizonal surface. When the block leaves the ramp it has a speed of 4 m.s a)what is the recoil velocity of the ramp b) how high is the ramp?

b. V^2 = Vo^2 + 2g*h
h = (V^2-Vo^2)/2g
h = (4^2-0)/19.6 = 0.82 m.
