A ball rolls onto the path of your car as you drive down a quiet neighborhood street. To avoid hitting the child that runs to retrieve the ball, you apply your brakes for 1.00 s. The car slows down from (14.51 + 4.50k )m/s to (8.257 + 3.50k )m/s. The mass of the car is 1.30 x 10* kg. (a) During the time the brakes were applied, what was the average force exerted on your car? Express your answer in vector form. F = -81251 - 1300k (b) How far did the car move while braking? 11.141 + 5.04k X Did you use the appropriate kinematic equation? m Additional Materials
