Why does a gun recoil?Derive the recoil velocity of a gun? |
| Answer» It recoils due to conservation of momentum of system.Iniatial momentum of gun = Final momentum of gun\xa00 = m1v1 + m2v2{tex}v_2 = -{m_1v_1 \\over m_2}{/tex}(-ve sign because velocity of gun is in opposite direction of bullet){tex}\u200b\u200b\u200b\u200b\u200b\u200b\u200bRecoil \\ velocity = -v_2 = {m_1v_1 \\over m_2}{/tex}Where\xa0m1 and m2 are masses of bullet and gun respectively\xa0v1 and v2 are velocity of bullet and gun respectively | |
