A fighter plane flying at an altitude of 1.5 km with a speed 72 km per hr passes directly overhead an anti aircraft gun. At what angle from the vertical should the gun be fired for the shell with muzzle velocity 600m/s to it the plane.(g=10m per secsqu.)(sin19.5deg = 0.333)

Question

Sher Mohammad · Answer

lets it is fired at angle&Oslash;, then at time t the bullet hit the plane 72*5/18 t= 600cos&Oslash; *t 1500=600sin&Oslash;*t-5t^2 20= 600 cos&Oslash; cos&Oslash;=1/3 sin&Oslash;=2sqrt(2)/3
