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. The correct relation between v_(0),a_(1),a_(2) and t_(0) is |

Answer» `v_(0)=((a_(1)a_(2))/(a_(1)+a_(2)))t_(0)^(2)` |
