A train starting from rest , pick up a speed of 10m/s in 100s . It continues to move at the same speed for the next 250s . It is then brought to rest in the next 50s . Plot a speed - time graph for the entire motion of the train. (i) acceleration of the train while accelerating (ii) retardation of the train while regarding (iii) and the total distance covered by the train.

for acceleration,
v=u+at
10 = 0 + a×100
a = 0.1 m/s2
for retardation,
appling the same above equation
we get a = -0.2 m/s2
for total distance
either get total distance by applying equatiins of motion or find out the area under speed - time graph
