Figure shows the accelerationtime graphs of a particle. Which of the following represents the corresponding velocitytime graphs?
Since acceleration is constant, therefore there is uniform increase in velocity. So, the graph is a straight line slopping upward to the right. When acceleration becomes zero, velocity is constant. So graph is a straight line parallel to the timeaxis.
