1. The problem statement, all variables and given/known data A car goes over a speedbump, which has the cross-section of a cylinder of radius R embedded in the roadway. If you want a car driving with a speed Vo to be impeded, how large must R be? I'm very confused about this problem because we have not discussed the topic in class and I have a terrible book. I want to say that you use the centripetal force equation, but that is for when velocity is constant? I'm not sure... Knowns: V initial = Vo V final = 0 mass = m Radius = height of the speed bump Unknowns: Radius 2. Relevant equations F = m(v^2)/R 3. The attempt at a solution Again, I am having trouble and do not know where to begin. I want to learn how to do this; not get a quick answer. Any and all help will be greatly appreciated.
