Question
Answer: Option A
:
A
The slope of a displacement-time graph gives us the velocity. The slope at any point in a curve can be found by drawing a tangent on it. In the figure, a tangent has been drawn at point A.
Slope=Change in y-coordinateChange in x-coordinate
At point A, clearly, there is no change in the y-coordinate. Hence, the slope is zero. This implies that the velocity at point A is zero.
