Vf=√(Vi^2 + 2ad)
Where
Vi=2.0m/s
A=9.8m/s^2
D=2.5m
You throw a ball downward from a window at a speed of 2.0 m/s. How fast (in m/s) will it be moving when it hits the sidewalk 2.5 m below?

h = -1/2 g t^2 - Vo t + 2.5 = -4.9 t^2 - 2.0 t + 2.5
set h = 0 , and solve for t (the time of flight)
Vf = Vo + g t
set h = 0 , and solve for t (the time of flight)
Vf = Vo + g t
