Procopio is driving a car (m = 1000 kg) at v1 = 11.11 m/s when he stepped on the brakes. The car traveled a distance of s = 15 m before stopping completely. How much force F was needed to stop the car? %3D The formula for the work done by the force F as the car traveled a distance s before stopping is: W = By the work-energy theorem: 2 W = - K1 = -½ Combining these two equations for work and isolating F, we obtain an expression for F: F = 20 Plugging in values, we know that 4.4 newtons of force is needed to stop the car.
