Angle of Launch

Variation of the launch angle of a projectile will change the range. If the launch velocity is known, the required angle of launch for a desired range can be calculated from the motion equations.

From the range relationship, the angle of launch can be determined. For range R = m = ft, and launch velocity v0 = m/s = ft/s. there are two solutions for the launch angle. θ1 = degrees, θ2 = degrees.
