The graph of displacement vs time for a particle moving along a straight line is as shown. The best option for the corresponding velocity - time graph will be:

Options

A.
B.
C.
D.

Answer

A

Explanation

Slope of displacement time graph is velocity. As we can see from the original graph, slope is initially positive. It decreases with time, becomes zero, and then becomes negative. Therefore, the velocity will also be initially positive,decrease to zero and then become negative. This means that (A) is the most appropriate option.
