I have no idea what a riser block is, or how the "leg" of a racetrack can be only 1 meter long. Where does the acceleration take place? The question makes no sense to me. Does it involve some lab experiment that you did?
Yeah this is from a physics lab. It was for a "Energy Works" lab where we trying to proof conservation of energy. Total energy = KE + Ug. We had a 2.2m long Dynamics Track with Dynamics cart. We used a "riser block" which was a wooden block to raise the Track. We push the cart and let it go from the bottom. Then, we catch it when it comes back down. Of course there would be some friction involved during this experiment.
