A train starts from rest and accelerates uniformly, until it has traveled 3 km and acquired a velocity of 20 m/s The train then moves at a constant velocity of 20 for 400 s. The train then slows down uniformly at 0.065 m/s2 until it is brought to a halt. Calculate the total distance the train travels. Make a distance versus time graph and a speed versus time graph of the trains motion

Dear student,... View the full answer

Let the initial velocity be u1,distance travelled be s1, time taken be t1, and
final velocity be v1. Similarly, when the train is moving at constant velocity,
the distance travelled is s2 and time...
