SUMMARY
A projectile achieves maximum range when launched at a 45-degree angle due to the optimal balance between vertical and horizontal components of its initial velocity. The range of a projectile can be derived using the formula R = (v^2 * sin(2θ)) / g, where R is the range, v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity. By applying basic calculus to this equation, one can confirm that the maximum range occurs at θ = 45 degrees.
