Question

*47. ssm The drawing shows an exaggerated view of a rifle that has been "sighted in" for a 91.4-meter target. If the muzzle speed of the bullet is Vo = 427 m/s, what are the two possible angles t, and θ2 be- tween the rifle barrel and the horizontal such that the bullet wi hit the target? One of these angles is so large that it is never used in target shooting. (Hint: The following trigonometric identity may be useful: 2 sin θ cos θ = sin 20.)
