To practice Problem-Solving Strategy 2.1 for problems involving kinematics with constant acceleration. A car is traveling at a constant velocity of magnitude v0 when the driver notices a garbage can on the road in front of him. At that moment, the distance between the garbage can and the front of the car is d . A time tr after noticing the garbage can, the driver applies the brakes and slows down at a constant rate before coming to a halt just before the garbage can. What is the magnitude of the car's acceleration after the brakes are applied
