Question

The graph of displacement v/s time is


Its corresponding velocity-time graph will be

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

We know that the velocity of body is given by the slope of displacement - time graph. It is clear that first the slope of the graph is positive and decreasing.

At the vertex (corresponding to the peak of the graph) the slope becomes zero.

After that the slope becomes negative and increasing.

So we are looking for a velocity curve which is first positive and decreasing then negative and increasing.
