Driving down the road at a speed of 24.6 m/s, you suddenly
notice a fallen tree blocking the road a distance of 54.6 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 6.8 m in front of the tree?
