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.

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.

You qualitatively analyzed the motion of a van earlier. Now, using the example of the ball thrown into the air, you can do a more detailed analysis of the van's motion. The table shown here includes the time and position data, with one worked example for finding acceleration.
