65. Range of a Projectile If a projectile is fired with velocity vD at an angle 0, then its range, the horizontal distance it travels (in ft), is modeled by the function vỗ sin 20 R(0) = 32 (See page 663.) If L' = 2200 ft/s, what angle (in degrees) should be chosen for the projectile to hit a target on the ground 5000 ft away?
