I know that work is the "dot product" of force and displacement, but I got a little stuck with this problem:
"Vera is driving her 1000-kg car at a speed of 8m/s. When Vera slams on the brakes, the ground exerts an 8000-N frictional force to bring the car to a stop. Determine the initial kinetic...
Can force or displacement be negative in the work equation?
Can force or displacement be negative in the work equation?
