    Need help with calculus for a car (admission test question)

    I thought that a system that is not accelerated has no resultant force (since you may neglect air and groung resistance). So, all the energy will be kinetic energy. E = (mv^2)/2. Then I got stuck in the second Question. So, I need the equation or a hint to solve question (b) and (c).

    Need help with calculus for a car (admission test question)

    In this question you will use a simple model to estimate how the energy used by a car depends on its design and how it is driven. Begin by neglecting air and ground resistance, and assume that the car travels at constant velocity between regular equally spaced stops. (a) A stationary car...
