Find the common final velocity after a perfectly inelastic collision in which two objects stick together and kinetic energy is not conserved.
输入两质量与碰前速度,求粘连共同速度。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Perfectly inelastic collision | v = (m₁v₁+m₂v₂)/(m₁+m₂) | Conservation of momentum (Newton 1687) |
| Energy loss | Lost KE goes to deformation and heat | Impact mechanics texts |
