Question

A Jet fighter flies horizontally at h=5000m with velocity u=100m/s. When the fighter flies directly over an air defense station, the station fires a gun as shown in the picture. The initial velocity for the projectile is V0=500m/s. Disregarding air resistance, find

1)At which angle (alpha) to the horizontal should the gun be to hit the fighter?

2)What is time t until impact with the fighter?

3)What is the horizontal distance s from the gun to the point of impact witht the fighter?

Explanation / Answer

100 = 500cosx ==>x = 78.46 deg. 1000 = 500sinx*t - 0.5*9.8*t^2 evaluate t.. i dont have calculator and s = 100*t
