If the angle of elevation of a cannon is $\theta$ and a projectile is fired with muzzle velocity $v$ ft $i$ sec, then the range of the projectile is given by the formula $$R=\frac{v^{2} \sin 2 \theta}{32} \text { feet. }$$ What angle of clevation maximizes the range?

Key Concepts

Range Formula

The range of a projectile is the total horizontal distance it travels during its flight. It is calculated using the initial velocity, angle of launch, and gravitational acceleration. Understanding the range formula is crucial for analyzing how changes in the launch angle or speed affect the distance covered by the projectile.

Projectile Motion

Projectile motion is the study of objects launched into the air and subject only to gravitational acceleration. It involves analyzing the separation of motion into horizontal and vertical components, which allows for the use of kinematic equations to determine parameters like time of flight, maximum height, and horizontal range.

Trigonometric Optimization

Trigonometric functions, particularly the sine function, play a key role in optimizing the range of a projectile. By leveraging properties of these functions, such as the fact that sine reaches its maximum value at a specific angle, one can determine the conditions that maximize the range.

Optimization in Physics

Optimization in physics involves finding the conditions under which a particular outcome, like maximum range, is achieved. This often includes setting derivatives to zero in a calculus-based approach or utilizing known function properties, enabling one to derive the optimal parameters for a given physical scenario.
