Initial Angle Calculator

Initial Angle Formula

The formula to calculate the initial angle is:

\[ \text{IA} = \frac{1}{2} \cdot \arcsin\left(\frac{g \cdot d}{v^2}\right) \cdot 57.2958 \]

Where:

• IA is the initial angle (degrees)
• d is the distance traveled (m)
• v is the initial velocity (m/s)
• g is the acceleration due to gravity (9.81 m/s²)

How to Calculate the Initial Angle?

1. Determine the distance traveled (m): Measure the distance the projectile travels horizontally.
2. Determine the initial velocity (m/s): Measure or estimate the initial velocity of the projectile.
3. Use the formula: Plug the values into the formula: IA = 0.5 asin(g d / v²) * 57.2958.
4. Calculate the initial angle: Perform the calculation to get the angle in degrees.

This tool simplifies the process of determining the initial launch angle for projectiles based on distance and velocity.
