a train starts from one station accelerates uniformly over a distance of 5 kilometre moves with a constant speed over 45 kilometres retards uniformly over the last 10 kilometre coming to a stop at another station 60 kilometre away from the first station draw velocity time graph of the train considering the motion to be in a straight line
Answers
Answer:
A velocity time graph is a graphical representation of the velocity of a moving object against time taken.
The graph of a velocity time graph gives the magnitude of acceleration of the moving body
Explanation:
The velocity of the train is given in the image attached.
Description of the graph
AB - In this segment, the train is moving with a uniform acceleration, over a distance of 5 kilometres, therefore there is increase in velocity with time.
BC - In this segment of the graph, the train moves over 45 kilometres with a constant speed. This means that the velocity remains constant ( there is no acceleration), meaning, velocity/speed remains constant with change in time. Therefore the graph plateaus ( flat or horizontal).
CD - The train in this point retards/decelerates uniformly over a 10 kilometre. This means that velocity reduces with change in time.
When the velocity of a moving object is represented graphically against the time taken to move is given by the velocity time graph The magnitude of acceleration with which the moving body is in motion can be determined by the velocity time graph The first part shows the train moving with a constant speed for a distance of 5 kilometer The second part shows the train moving Til 45 kilometer with a constant speed.while third part shows a constant retardation for 10 kilometers.
