1. The problem statement, all variables and given/known data A body of mass m is moving through a bumpy road. the distance between each 2 bumps is 2h and the height of every bump is h. The body starts at velocity V0 and stops on top of the third bump. The friction coefficient is μ. Ignore the acceleration needed to change the direction on every peak, and the shape of the bumps is unknown. What is the work of the friction force between the second and third peaks? What is V0 and what is the velocity on every peak? 2. Relevant equations Work-Energy theorem 3. The attempt at a solution I tried to find the the work using the work-energy theorem, but i realized I couldn't find the normal force since i don't know the shape of the path, and I have no idea how to do the line integral if i don't know the shape. In other words, i'm stumped.
