Help please! I tried solving it but I can barely tell what I should do first. A car moving at a velocity of 20 m/s is behind a truck moving at a constant velocity of 18 m/s. When the car is 50 m behind the front of the truck, the car accelerates uniformly at 1.8 m/s. The car continues at the same acceleration until it reaches a velocity of 25 m/s, which is the legal speed limit. The car then continues at a constant velocity of 25 m/s until it passes the front of the truck. a) What is the distance the car travels while accelerating? b) What is the time interval from the point that the car reaches the speed limit until it passes the truck? Thanks!
