Vedclass · Answer

(A) The acceleration $a$ of a body is given by the slope of the velocity-time $(v-t)$ graph,i.e.,$a = \frac{dv}{dt}$.In the given $v-t$ graph,the velocity decreases linearly with time initially,which means the slope is constant and negative. Thus,the acceleration is constant and negative.After reaching a minimum velocity,the velocity increases linearly with time,which means the slope is constant and positive. Thus,the acceleration is constant and positive.Comparing this with the given options,the graph that represents a constant negative acceleration followed by a constant positive acceleration is option $A$.

The graph below shows the velocity versus time graph for a body. Which of the following graphs represents the corresponding acceleration $v/s$ time graph?
