Homework Statement
A ball is thrown vertically upward from a window at 10m/s. It hits the ground 5.0 seconds later. What is the height of the window from the ground?
Given
Vi = 10 m/s
Vf = 0
Δt = 5.0 m/s
[tex]Δa = -9.8 m/s^2 [/tex]
Find
Δd(w-g) = ?
Homework Equations
Δd = Vi(Δt) + [itex]Δa(Δt)^2[/itex]
And the other four "kinematic equations"
The Attempt at a Solution
Total displacement:
[tex]Δd = ((vi + vf)/2)(Δt)[/tex]
= (10/2)(5)
= 25 m
Not sure where to go from here and if I'm on the right track. Your help is greatly appreciated!
P.S. I apologize for the terrible formatting. I'll get it soon enough!
