V-t graph when ball throws up?pls help nd see doubt in my comment

Answer 1

Answer:

Key points to note when sketching the v-t graph:

1) Fixing the direction up to be positive (can be down as positive if you want)

2) At t = 0s, the initial velocity of the ball is maximum.

3) As it goes up vertically, due to the weight acting downwards, the ball decreases in speed (decelerates)

4) At the highest point, the ball is momentarily at rest (v =0m/s)

5) On the way down, due to the weight of the ball acting downward, the ball accelerates downwards.
