Question

I was thrown up a stone towards the sky by the acceleration of 20m/s2
What was the acceleration of stone when it comes to ground?

Answer 1

Answer:

When a body comes down it experienced gravitation acceleration i. e. 9.8 m/s(power2) so it's acceleration is 9.8 m/s(power2).

Answer 2

It will be 9.8 m/s^2

Suppose the body goes from point P to P' upwards where the velocity would be 0. Now, it starts coming downwards from P' to O (the ground level). We know that the would would accelerate uniformly for the gravitational pull. Hence, the body (stone) would have an acceleration of 9.8 m/s^2 at any point while it comes back.

HOPE THIS COULD HELP !!!
