Formula and methodology
Formula: Speed = √(2K/m).
The result is the speed implied by the entered kinetic energy and mass under a classical mechanics model.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Projectile mass — kg; minimum 1.0E-6; maximum 1000000
- Kinetic energy — J; minimum 0; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Projectile mass | 0.05 |
| Kinetic energy | 50 |
Speed ≈ 44.721 m/s.
Assumptions and limits
- Mass is in kilograms and energy is in joules.
- The energy is translational kinetic energy at the measured point.
- Air drag, launch efficiency, arrow flex, broadheads, target interaction, and safety are not modeled.
