A car accelerates from rest at a constant rate o for some time after which it decelerates at a constant rate B to come to rest If the total time elapsed is t evaluate a the maximum velocity attained and b the total distance travelled a Let the car accelerates for time t and decelerates for time t then t t 1 and corresponding velocity time graph will be as shown in fig 1 31 0 t From the graph a slope of line AB and slope of line OB 11 max a B t v max t a V 1 b Total distance area under v t graph max t v B max 1 2 a a t a B xtxv max 1 2 t xtx a t a B 1 a t 2 B
