In Figure as shown above the velocity of the body at A is:
Open in App
Solution
The correct option is A zero
For curved graphs, slope at a point is calculated by drawing a tangent at that point. At point A, tangent is parallel to time axis, means slope is zero. Therefore, velocity at point A is zero as slope of displacement-time curve gives velocity.
