Two blocks are moving along a horizontalfrictionless surface. The 4 kg block is moving to the right with aspeed of 6 m/s and the 2 kg block is moving to the left with aspeed of 3 m/s. The two blocks collide inelasticallyand then continue to move together alongthe surface and then up a 30° frictionless ramp. How high upthe ramp does the combined object move?
