After making corrections for azimuth and elevation, provided by a forward observer, a very powerful army artillery gun is now assumed to be lined up to hit a target 54.6 mi away. (i) If the muzzle velocity of the projectile out of the gun is 3200 ft/sec, and it is fired at an angle of 33 degrees made with the horizontal (and we neglect air friction & Earth rotation) then it will miss a direct hit on the target by only about _______mi. (ii)The maximum vertical height reached by the projectile is about __mi.
