Question

the graph of displacement versus time of a body is a straight line making a positive angle with x-axis . then the instantaneous velocity of the body at any point is ?
​

Answer 1

Answer:

Slope of the displacement-time graph gives the instantaneous velocity (speed) of the object.

From the graph, at point P and Q, slope of the graph is decreasing and thus the speed of the object is also decreasing.

At point R, slope of the graph is increasing and thus the speed of the object is increasing

Answer 2

Answer:

Equal to the average velocity of the body
