Q. Figure shows the acceleration-time graphs of a particle. Which of the following represents the corresponding velocity-time graphs?

A) [image:3_image109.emf]
B) [image:3_image110.emf]
C) [image:3_image111.emf]
D) [image:3_image112.emf]
Explanation

(b) Since acceleration is constant, therefore there is uniform increase in velocity. So, the $v - t$ graph is a straight line slopping upward to the right. When acceleration becomes zero, velocity is constant. So $v - t$ graph is a straight line parallel to the time-axis.
