A car starts from rest and accelerates to a speed of "a" mph in "c" seconds. The acceleration during this period is constant. For the next "d" minutes the car moves with the constant speed of "a" mph. At this time, the car decelerates to a speed of "b" mph in "e" seconds. Then for the next "f" minutes the car moves with a constant speed of "b" mph. At this time the driver of the car applies the brake and the car decelerates to a full stop in "g" seconds. The variation of the speed of the car with time is shown in the accompanying diagram. Determine the total distance (miles) traveled by the car and the average speed (kph) of the car over this distance. a = 50 mph b = 30 mph 30 seconds d = 30 minutes e = 20 seconds 25 minutes f3= 10 seconds

A car starts from rest. It accelerates at constant acceleration for 5.0 seconds during which the car covers a distance of 125 m. After that the car continues at that speed for 22 seconds, after which the car slows down at a constant deceleration of – 4.5 m/sec2 until coming to a complete stop. Draw a v vs t, graph, label all the relevant data, and use the graphical method to determine total distance traveled.
