STANDARD Physics Conservation of Momentum MCQ Question
A shell of mass 200 g is fired by a gun of mass 100 kg. If the muzzle speed of the shell is 80 m s⁻¹, then the recoil speed of the gun is
16 cm s⁻¹
8 cm s⁻¹
8 m s⁻¹
16 m s⁻¹
Correct Answer
Detailed Explanation
Using the conservation of linear momentum, mV + Mv = 0, where m is the mass of the shell and M is the mass of the gun. Solving for v, the recoil speed of the gun, we find it to be 16 cm s⁻¹.
