- you are driving down the road and are speeding. You apply the brakes on your car until you slow down to 22.4 m/s. A computer plots the force versus time for the vehichle and then measures the area under the curve. The area is -18950 N per s. The total breaking is 5.4 seconds. The combined mass of the car is 1200 kg. How fast were you moving before applying the breaks? What is the average force applied by the road to thr car before breaking?arrow_forwardou are pushing your friend in his wheelchair. You are both taking his dog, Wrathbone, to the vet.
