Driving down the road at a speed of 37.0 m/s, you suddenly notice a fallen tree blocking the road a distance of 90.7 m ahead of you. You step on the brake pedal and decelerate at a constant rate. What must the magnitude of your acceleration be so that you will come to a stop 8.2 m in front of the tree? 8.30 m/s^2 7.55 m/s^2 6.92 m/s^2 16.59 m/s^2
