The driver of a car slams on the brakes when he sees a tree blocking the road. the car slows uniformly with acceleration of −5.25 m/s2 for 4.15 s, making straight skid marks 62.5 m long, all the way to the tree. with what speed (in m/s) does the car then strike the tree? you may want to calculate the initial velocity of the car first. m/s (b) what if? if the car has the same initial velocity, and if the driver slams on the brakes at the same distance from the tree, then what would the acceleration need to be (in m/s2) so that the car narrowly avoids a collision? m/s2
