The velocity-displacement graph of a particle is shown in the figure. The acceleration-displacement graph of the same particle is represented by :

<p> (v/v? ) + (x/x? ) = 1 ⇒ v = - (v? /x? )x + v? </p><p>⇒ a = dv/dt = - (v? /x? ) (v) = - (v? /x? ) [- (v? /x? )x + v? ] ⇒ a = (v? ²/x? ²)x - v? ²/x? </p><p><img ></p><ul type="disc"><li>Concept involved: Graph of kinematics</li><li>Topic: Kinematics</li><li>Difficulty level: Moderate</li><li>Note: IIT-Jee-2005</li><li>Point of Error: Writing Equation of straight line and differentiation</li></ul>
