1. The problem statement, all variables and given/known data The speed of a car increases uniformly with time from 50km/hr at A to 100km/hr at B during 10 seconds. The radius of curvature of the bump at A is 40m. if the magnitude of the total acceleration of the car’s mass center is the same at B as at A, compute the radius of curvature of the dip in the road at B. The mass center of the car is 0.6m from the road. 2. Relevant equations an=VB2/ρ 3. The attempt at a solution Before I solve this problem, I want to get some conceptual questions out of the way. It says the magnitude of acceleration is constant, does this mean that the normal and tangential components of acceleration are constant from A to B? If so can I just compute an=VA2/ρ at A and use that for an at B?
