Posted by The range of a target is found to be 20km. A shell leaves a gun with a velocity of 500ms-1. What must be the angle of elevation of the gun if the ground is leueled? on Wednesday, February 1, 2012 at 8:55am.
That's quite a long name you have.
R = (Vo^2/g)*sin(2A) = 20,000 m
sin(2A) = 0.785
2A = 51.7 or 128.3 degrees
A = 25.85 or 64.15 degrees
