A car drives at constant speed of 15 m/s in 5.0 seconds, then it speeds up to 25 m/s in 6 seconds by constant acceleration, it holds that speed for 4 seconds and then the car stops with a constant acceleration at a 55 meter distance.

a) Draw a vt-graph of the cars motion until it stops.

b) Use the vt-graph to compute the whole distance that the car went.

c) Use the slope of the vt-graph to discover acceleration of the car when it is still.

d) Compute the average speed of the car and use vt-graph to show the speed.
