Question

Using the average vertical range and the height, calculate the initial velocity (muzzle velocity) using equations 5,6,7, & 8.

x-coordinate axis 5y.) xf = (1/2)·ax·(Δt) 2 + vix·Δt + xi r = (1/2)·(0 m/s2 )·(Δt) 2 + vix·Δt + (0 m) 5x.) r = vix·Δt y-coordinate axis

6y.) yf = (1/2)·ay·(Δt) 2 + viy·Δt + yi 2y.) (0 m) = (1/2)·(-g)·(Δt) 2 + viy·Δt + (h) where g = 9.8 m/s2 where vix and viy are the components of the initial velocity, vi:

7.) vix = vi · cos Θ

8.) viy = vi · sin Θ

Average Range: 5.05 m

Height: 1.18 m

Angle: 0
