Problem: You release a frictionless cart at the top of each of the 2 ramps. BOTH CARTS ARE RELEASED FROM REST. The ramps have the same height as each other at the starting and finishing points. One has a small bump up then down before the end. The other has a small bump down then up. Which cart has the larger speed at the finish and why?

🤓 Based on our data, we think this question is relevant for Professor Leduc's class at SDSU.

Energy conservation,

mgh0+12mv02=mghf+12mv2

The initial and final heights for the two carts are the same.
