1. The problem statement, all variables and given/known data "A hot-wheels car of mass 0.0250 kg is traveling on a horizontal track with a velocity of 5.00m/s. If the track suddenly turns upward, how high up the track can the car travel?" 2. Relevant equations work = mgh = force * distance PEf + KEf = PEi + KEi KE = .5mv^2 3. The attempt at a solution I know that I need to find the distance, so I solve the work equation so it looks like (mgh)/force = distance. However, this is where I'm stuck. What would I use for the height of the ramp? Also, what would I use for the acceleration (I currently have F = ma in the equation, so the masses cancel and what's left is (gh)/a)? Would I use gravity?
