Question

Let's say you measure an average acceleration to be 0.3883 ms-2.
What is the height (in centimeters) of the riser block?
Assume the legs of the track span 1.0000 m and that there is neither friction nor drag. Also assume the block is under one of the legs.
cm
Use three significant figures or N/A if not enough information is given.

Answer 1

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?

Answer 2

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.
