The displacement-time graph for two particles A and B are straight lines inclined at angles of 30^(@) and 60^(@) with the time axis. The ratio of velocities of V_(A) :V_(B) is

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 velocity-time graph for two objects P and Q are shown. The ratio of their respective acceleration is

The x-t graph of an object is a straight line inclined to time-axis. What does this statement indicate ?
