A car travelling on a straight road starts from rest and accelerates at 2.0 m/s2 until it reaches a speed of 20 m/s. Then the car travels for 20 s at constant speed until the brakes are applied, stopping the car in a uniform manner in an additional 5.0 s. Determine: the time the car has been in motion. the total distance travelled. the average speed of the car during the motion.

A swimmer pushes off a wall from rest where she has a constant acceleration of 2m/s2 for 1.5 seconds. She then continues for 10 seconds at constant velocity. At this point, a) How far away from the wall is she if the pool is 50m? b) If she then glides to a stop, what was her deceleration rate? c) Draw the position verse time graph, velocity verse time graph, and acceleration verse time graph. You can assume all accelerations are constant. d) Now take your velocity verse time graph and re calculate the distance covered by the swimmer.
