Homework Statement This is a conceptual question for a lab. In the lab we used two gliders on a nearly frictionless airtrack on a level surface, with photogates set up to measure the velocities of the two gliders before and after the collisions. The second glider was initially stationary...

Ok, no thanks to you, I got it. I replaced -9.8 with -9.8sin25. Next time don't be so cryptic! :(

Please oh please, I appreciate your help, but I really wish you would stop being so cryptic. I breezed through my other physics problems and this one has had me going for an hour. I am exhausted and want to sleep. Please explain the concept behind what you are trying to say, clearly? You don't...

Mass is not given, and we haven't even done force yet. I know about force caues I did it last year but I really don't think this problem should involve force.

That is what I did, and it was marked wrong.

Ok... but how do I find the acceleration if I don't know the distance it traveled?

Homework Statement A car traveling at 22.0 m/s runs out of gas while traveling up a 25.0 degree slope. How far up the hill will it coast before starting to roll back down?Homework Equations Vf^2 = V0^2 + 2ax x = V0t + (1/2)at^2 (maybe?)The Attempt at a Solution I am using an online homework...
