The driver of a car wishes to pass a truck that is traveling at a constant speed of 19.0 m/s . Initially, the car is also traveling at a speed 19.0 m/s and its front bumper is a distance 24.3 m behind the truck's rear bumper. The car begins accelerating at a constant acceleration 0.640 m/s2 , then pulls back into the truck's lane when the rear of the car is a distance 25.7 m ahead of the front of the truck. The car is of length 4.40 m and the truck is of length 21.7 m .How much time is required for the car to pass the truck?
