Hi, and welcome to QuestionCove! This is a question involving calculating work, which we can find by taking the force exerted multiplied by the displacement over which the force was exerted. The displacement part is simple to calculate, since we are told how much distance the car travels. As for the force exerted by the car, we know the mass of the car... any idea how we can calculate force based on that information?
