A sports car is to travel from A to B in exactly 40 seconds. The distance between A to B is 540 m. The car accelerates at 1.8 m/sec2, then travel at a constant speed for some time before it decelerates at 1.8 m/sec2. The car starts from rest at A and comes to rest at B. Find the maximum speed. Draw the a-t, v-t and s-t graphs to solve the problem.
