In physics lab, a cube slides down a frictionless incline as shown in the figure below, and elastically strikes another cube at the bottom that is only one-half its mass. if the incline is 30 cm high and the table is 90cm off the floor, where does each cube land [hint: both leave the incline moving horizontally]

­The speed after falling from a certain height can be calculated using the energy conservation.
