Answer» igure shows position versus time GRAPH of two rabbits running opposite to each other between two trees.To find:Which rabbit has higher average velocity ?CALCULATION:Average velocity is defined as the RATIO of the total displacement to the total time taken to complete the displacement.Now , avg. v = ∆x/∆t , so we can say that:The slope of the the displacement time graph gives US the instantaneous velocity.But when an object is moving in a SINGLE directions, average velocity is directly proportional to the instantaneous velocity of the object.So, higher the slope (steep-ness) of curve , higher will be the average velocity for that rabbit.Since the graph for rabbit B is steeper , hence it has higher average velocity than rabbit A.
