Question

A train starting from one station escalates uniformly over a distance of 5 kilometre moves with a constant speed over 35km returns uniformly over the last 10 kilometre coming to a stop another station 5 km away from the first citizen draw velocity time graph of the train

Answer 1

Answer:

A train that escalates uniformly over 5 kilometres, then moves with constant speed over 35 kilometres and finally retards uniformly over the last 10 kilometres to a stop, will have the following velocity time graph:

A velocity time graph is a graphical representation of the velocity of a moving object against the time taken by the moving object.

Explanation of the graph:

The velocity time graph is attached in the image below:

AB -  In this segment, the train moves with a uniform escalation/acceleration which means the train's speed/velocity is increasing with time. The graph rises as show in the part AB.

BC - In this segment of the graph, the train moves with a constant speed( zero acceleration or no change in velocity). Therefore the graph is flat and plateaus in the manner portrayed between B and C.

CD - In this segment, the graph is falls steadily due retardation. The train's velocity decreases with time as shown in the graph between C and D.
