    A horizontal force of 5.0N acts on a 3.0kh mass over a distance of 6.0m along a horizontal frictionless surface. What is the change in the KE of the mass?

    it would be equal to w = mgd?

    A 14, 700 N car is traveling at 25.0 m/s. The brakes are applied to stop as per attached figure . The average breaking force is 7100N - how much energy does the car lose in order to stop?

    - how much work is done on the car in order to stop it? - how far will it take the car to stop?

    All of these make use of the work-energy theorem. \[W = \Delta U\]where \(\Delta U = \Delta KE + \Delta PE\)
