Horizontal Motion

Δx = VxΔt

Vx = Vxi = constant

Vertical Motion

Δy = +½ g •(Δt)2

Vyf = +g •Δt

Vyf2 = +2g •Δy

Overall Final Velocity

Vf2 = Vx2 + Vyf2

Δx = Vi (cosθ) •Δt

Vxi = Vi (cosθ)  remains constant

Vyi = Vi(sinθ)

Δy = Vi(sinθ) • Δt + ½ g •(Δt)2

Vyf = Vi(sinθ) + g •(Δt)

Vyf2 = Vi2(sinθ)2 + 2g •(Δy)

Overall Final Velocity

Vf2 = Vx2 + Vyf2
