Question

A stone is thrown upward with initial velocity of 50 metre per
second after sometime the stone comes back to the ground draw a
velocity time graph and an acceleration time graph for this motion. ​

Answer 1

Answer:

The graph shows change in velocity with respect to time and you can observe that the velocity first decreases and reach 0m/s at time Fifth second (after the stone is thrown) then after that its velocity increases and reach again 50 m/s on the 10th second.

NOTE .: The velocity at first from 0 to 5 second is in upward direction while after 5 second is in downward direction.

The initial velocity with which a body is thrown upward is always equal to the final velocity with which it reach the earth back (which is 50 m/s in this case)

2) As the acceleration = g = 9.8m/s2

is constant all over the journey so the acceleration time graph would be a staight line parallel to the time axis.
