A car starts from rest and accelerates at a rate of 4.53 m/s2 for 5.12 seconds. The driver spots a tree blocking the road ahead and slams on the brakes after a reaction time of 0.317 seconds. The car screeches to a halt after 3.74 seconds, just short of hitting the tree. After the first 5.12 seconds the car is traveling with a speed of 23.2 m/s. The car travels 13.1 m as it speeds up. The car travels 7.35 m during the reaction time. What is the acceleration of the car as it comes to a stop? What is the distance of the tree from the ORIGINAL starting point?
