Calculate the height from from which a body is released from rest if its velocity just before hitting the ground is30m\s

height = 45 m

Explanation:

Initial velocity = 0 m/s

Final velocity = 30 m/s

Acceleration due to gravity = +10m/s^2 ( because ball is going down )

Using the eqn of motion

where v= final velocity ; u = initial velocity ; g = acceleration due to gravity ; h = height

So,

whichever one it is, it's definitely not one that you included on the list you provided.

im sorry i dont know
