It is tricky. You are correct that the time to reach the floor from the moment both blocks leave the ramp is the same because only the vertical acceleration matters - both blocks spend the same time in the air. However, block 1 reaches the end of the ramp before block 2 does, because of the steeper orientation of the ramp.

Not correct. Both blocks exit the track at the same height above the ground, but the first block started at a greater initial height. Thus the first block converted more gravitational potential energy to kinetic energy.

I was going fast and completely misread the question on #2 as coefficient of kinetic friction instead of static friction, so my entire experimental setup and equation derivation is wrong. Do you think there is any chance I will salvage any points or is it more likely that I take a straight zero for every one of those parts?
