In a physics lab, a small cube slides down a frictionless incline as shown, and collides at the bottom (where it is now moving horizontally) with a cube that is only one-half its mass. If the incline is 30 CM high and the table is 90 CM off the floor. where does each cube land? the teacher gave us that the big cube lands 30 CM away. Thats all, does anyone know how to solve this?
