Problem 6 - Conservation of energy / momentum Suppose that a block of mass mi = 0.3 kg slides down a frictionless halfpipe from a starting height hi = 2 m and collides with a second block of mass my = 0.1 kg at the bottom. If the two blocks then slide together, . What is the speed of the two blocks just after they collide? (10 points) . What is the maximum height h that these two blocks will reach before sliding back down? (10 points)
