A ball is thrown vertically upward from a window with an initial velocity of 10m/s. if it hits the ground below the window 5.0s later, what is the height of the window...can you tell me the steps on how to do this please...

Answer 1

assume all heights are from the middle of the window.
hf=hi+vi*t-1/2 g t^2
hf=unknown
hi=zero
vi=10
t=5
g =-9.8m/s^2
calculate
