Question

A car A starting from rest accelerates uniformly at the rate of 2ms-2 for a 10s and another car B initially moving at a speed of 72km/h decelerates uniformly at the rate of 2ms-2 and comes to rest in  10s.Both the cars are moving in straight line path. Derive the data for the speed –time graph from the equation v =u+at and plot both  the graphs in the same graph sheet.

Calculate the distance travelled by the both the cars .
Do both cars have same speed at any time.If so mention the time and the speed of the cars.
