Which statement accurately describes the velocity of the object in the graph above over the six seconds?

Option A

Explanation:

The object started from rest and moves forward at 5 m/s for 2 seconds at uniform rate of motion, after that maintained constant speed of 10 m/s for next 2 seconds and in the last 2 seconds the object comes down to rest again with uniform decrease in it's motion at the rate of 5 m/s.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
