SUMMARY
The maximum distance a projectile can travel occurs at a launch angle of 45 degrees due to the mathematical relationship defined by the range formula, R = (v0^2 * sin(2α)) / g, where α is the launch angle and g is the acceleration due to gravity. The term sin(2α) reaches its maximum value of 1 when 2α equals 90 degrees, confirming that α must be 45 degrees for optimal range. This conclusion is derived from kinematic equations and the properties of trigonometric functions.
