1.

Acceleration versus time graph for four objects are shown below. All axes have the same scale. Which object had the greatest change in velocity during the interval ?A. .B. .C. .D. .

Answer» Correct Answer - D
In option (b) area of graph is `(1)/(2) t_0 a_0`. But in options (a) and ( c) area is less than `(1)/(2) t_0 a_0`. In option (d), area is more than `(1)/(2) t_0 a_0`. So in option (d) change in velocity is greatest.
