[SOLVED] Rifle shot
A rifle that shoots bullets at 475 m/s is to be aimed at a target 42.5 m away. If the center of the target is level with the rifle, how high (in cm) above the target must the rifle barrel be pointed so that the bullet hits dead center?
sin(2theta) = gd/v0^2
So sin(2theta) = (9.8)*(4250)/(47500^2) = 1.84598338e-5
So sin(2theta) = ?
