I am having a hard time trying to figure out this problem: What is the max speed that you can drive the car over the top of the bump without losing contact with the road. I have the radius= 66.7 m, constant speed of car = 16.4m/s, and weight of your passenger=57.0kg. With these numbers I was able to find the apparent weight of passenger as you pass over the top of the bump= 329.3 N. I just dont know how to find the speed need to not lose contact. Some one please help. Thanks a lot!
