Courses: P3, P13
This is the same setup as the flat version (1D60.10), but the track is propped up on an incline. Start the cart from stationary, and release it. It will also work if you send the cart up the track from the bottom.
One can take a video to analyze the motion, or use a strobe light. It can be seen that the ball remains centered over the cart relative to the incline, but not necessarily relative to the horizontal.
