A train starts from rest and starts with constant acceleration a = 3.6 m/s2 for 28 s. The train then coasts at constant velocity for 118 s. The train then comes to rest in 14 s. Please find the total distance covered by the train during the 160 s described. Kinematic equations: V = vo + at, x = x + vot + at", v = vi + 2aAx, x = x, + (v + v.)t.

Answers

For Ist part of motion, u=0 a=3.6 m/s2 = 285 So, v= at = 3.6 X 28 = 100.8 mis S= ut + ļ at 2 = 3.6*1 x 282 = 1411.2m. Now for
