a truck travels a distance d=22.1m in the positive x direction in a time t1=17.7s, at which point the truck brakes, coming to rest in t2=9.53s. Assuming the truck started from rest and moved with a constant acceleration, what was the acceleration, in meters per squared second, during time interval t1 and what was the truck's instantaneous velocity in the horizontal direction, in meters per second, when it began braking?
