Calculate the magnitude of the recoil velocity of a 5.0 kg rifle that shoots a 0.050 kg bullet at a speed of 130 m/s.
Vipender Y.
A gun fires a bullet of mass $40 \mathrm{~g}$ with a velocity of $50 \mathrm{~m} / \mathrm{s}$. Because of this the gun is pushed back with a velocity of $1 \mathrm{~m} / \mathrm{s}$. The mass of the gun is (A) $1.5 \mathrm{~kg}$ (B) $3 \mathrm{~kg}$ (C) $2 \mathrm{~kg}$ (D) $2.5 \mathrm{~kg}$
A bullet weighing $50 \mathrm{gm}$ leaves the gun with a velocity of $30 \mathrm{~ms}^{-1}$. If the recoil speed imparted to the gun is $1 \mathrm{~ms}^{-1}$, the mass of the gun (A) $1.5 \mathrm{~kg}$ (B) $15 \mathrm{~kg}$ (C) $20 \mathrm{~kg}$ (D) $30 \mathrm{~kg}$
