SUMMARY
The force exerted on a 5.0g bullet leaving a rifle with a speed of 320 m/s can be calculated using Newton's second law, represented by the equation ΣF = ma. The bullet travels down a 0.82 m long barrel, and applying the work-energy theorem, W = ΔE_k, provides a straightforward method to determine the force. The calculations yield a constant force acting on the bullet during its acceleration within the barrel.
PREREQUISITES
- Understanding of Newton's second law (ΣF = ma)
