The Impulse is what is expected in the answers, not the Force. 

The automobile has a weight 3,284-lb and is traveling forward at 8ft/s when it crashes into the wall. The impact occurs in 0.02 s. 1. Determine the average impulsive force during the impact if the brakes are not applied. 2. If the coefficient of kinetic friction between the wheels and the pavement is 0.44, and the brakes are applied what is then the average impulsive force?
