Hi Guys, we were given this question, and I have no idea where to start. A car is coasting without friction toward a hill with height 'h' and ratius of the curvature is 'r'. (a) what initial speed 'vo' will result in the car's wheels just losing contact with the roadway as the car crests the hill? (b) what happens if the initial speed of the car is greater than the value found in part (a)? I have figured out that there are no non-conservative forces acting on the car, so the work (conservative) is equal to the work (total) but I dont know where to go from there...any suggestions?
