Question
The graph of displacement 
time is Its corresponding velocity-time graph will be
The correct answer is:
We know that the velocity of body is given by the slope of displacement 
time graph so it is clear that initially slope of the graph is positive and after some time it becomes zero (corresponding to the peak of graph) and it will become negative
