A ball is dropped out a wimdow that is 36 feet high. how long does it take for the ball to hit the ground

36 feet to metres = 10.97

first find the final velocity

vf^2 = vi^2 + 2ad

vf^2 = 0 + 2 (9.81) (10.97)

vf^2 = 215.2314

vf = 14.6708

vf = vi + at

at = vf - vi

t = (vf - vi) / a

t = (14.6708) / 9.81

t = 1.4955seconds
