Question

draw the velocity-time graph of a stone thrown vertically upward with initial velocity u and then coming downwards after attaining the maximum height h. Use appropriate marking on the velocity Time Scale. The acceleration due to the gravity is g vertically downwards. Also draw the position time graph​

Answer 1

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.
