(adsbygoogle = window.adsbygoogle || []).push({}); Kinematics Question plz help.

1. The problem statement, all variables and given/known data

a ball is thrown vertically upward from a window that is 3.6m above the ground. Its initial speed is 2.8m/s . What speed will the ball hit the ground.

show what formulas were used plz.

2. Relevant equations

v2^2=v1^2+2ad

3. The attempt at a solution

im wondering, wouldnt the height be different, because it is thrown vertically up?

so the distance would be different, changing the speed (Vf)?

I get 8.85m/s when i assume d=3.6m Vo=2.8m/s a=9.8m/s

wouldnt that be the speed of the object if it were thrown to the ground?
