Another idea from Kelly, students were given the ramp angles and that the shallow ramp cart will be released from the 1 meter mark, then had to find where the 2nd cart should be released from such that they hit the end stops at the same time. A note, turns out the ratio of the angles is very close to the ratio of the sines of the angles, so you either can’t let them test till they have physics that supports their answer, or find a way to maximize the difference between the two ratios so it is obvious that the ratio of just the angles doesn’t work.
