Question

A bus of mass 2500 kg is moving with a velocity of 10 m/s. If the velocity-time graph for this bus is a horizontal line parallel to the time axis, then the velocity of the bus at the end of 25 seconds will be

Answer 1

Hi Friend!!!

Since velocity line is parallel to time, slope of the graph                                      = change in v / change in time

v remains constant, so slope is 0.

That means acceleration is 0.

So, since velocity remains constant, no matter for what point of time, the velocity is same and equal to 10 m/s
