362319 A metro train starts from rest and in \(5 s\) achieves \(180\,km{h^{ - 1}}\) After that it moves with constant velocity and comes to rest after travelling \(45\;m\) with uniform retardation. If total distance travelled is \(395\;m,\) find total time of travelling.

362320 A truck is moving at a speed of \({72 {kmh}^{-1}}\) on a straight road. The driver can produce deceleration of \({2 {~ms}^{-2}}\) by applying brakes. The stopping distance of truck is \({13 x {~m}}\), if the reaction time of the driver is 0.2 s . The value of \({x}\) is

362321 Assertion :
The displacement -time graph of a body moving with uniform acceleration is a straight line.
Reason :
The displacement is proportional to time for uniform motion.

362322 A car, starting from rest, accelerates at the rate \(f\) through a distance \(S\), then continues at constant speed for time \(t\) and then decelerates at the rates \(\frac{f}{2}\) to come to rest. If the total distance travelled is 15 \(S\), then
