Imagine we have created layers of ice on the surface of a platform and then propped it up at  an angle of 10° with the ground. This makes a ramp 10 ft long from one end to the other. We then  place the 5 kg cube at the top of the ramp and let it go. How long will it take for the cube to  reach the end of the 10 ft ramp?
