Question

draw a velocity versus time graph of a stone thrown vertically upward and then coming downwards after attaining the maximum height

Answer 1

this is your answer.
keep asking.
thanks.

Answer 2

Answer:

Let the initial velocity=u m/s

Let ' t' be the time taken to reach the maximum height h.

At maximum height, velocity becomes zero and the ball starts it's backward journey .

Here in the graph, we can see that velocity in backward journey increases but in negative direction till the stone reaches to ground.

Please refer the attachment for velocity time graph.
