Question

A ball is thrown vertically upward and then it come back to the hands of the thrower plot the speed time graph of the ball
​

Answer 1

Hey mate how can we plot graph here

But i can tell you that you the graph is straight line with slope as -g

Answer 2

Answer:

Explanation:

When a ball is thrown upward, it gains speed from the initial velocity of 0 and may take a few seconds to reach a maximum topmost point against the gravitational force.

At that point, its velocity is maximum, before it starts falling down to the thrower. The falling speed is influenced by the gravitational force, which is constant all the time.

So the graph changes from the highest point in speed while the time is 0, to the time taken by the ball while the speed gradually decreases to the lowest point. Then the speed again increases as the ball falls down, along with the increase in the time needed for falling.
