1. The problem statement, all variables and given/known data 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) = ? 2. Relevant equations Δd = Vi(Δt) + [itex]Δa(Δt)^2[/itex] And the other four "kinematic equations" 3. 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!
