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?

- An old phrase used to sell cars was that they could "stop on a dime," meaning they could stop before the car moved a distance equal to the diameter of a dime. a. To see if this is realistic, calculate the net force needed to stop a 490-kg car moving at 25 miles/hour in a distance of 1.8 cm (the diameter of a dime). b. Compare that force to the weight of the car. Are they even close to the same size? Based on your comparison, is "stopping on a dime" a reasonable claim, or is the force needed unreasonably large? c.
