Graphs are very useful to represent a physical situation. Various quantities can be easily represented on graphs and other quantites can be determined from the graph. For example the slope of velocity-time graph represents instantaneous acceleration. For a motion with constant acceleration slope of velocity-time graph is constant. If acceleration is changing with time, slope with change and thus velocity-time graph will be a non-linear curve. Further the area of velocity-time graph gives displacement. A car starts from rest with a constant acceleration `a_(1)` for some time and attains a velocity `v_(0)`. Then it immediately retards at a constant rate `a_(2)` to rest. The total time to journey is `t_(0)` Identify the correct velocity-time graphA. B. C. D. None of these
