A bullet of mass 0.1 kg is fired with a speed of 100 m/sec, the mass of gun is 50 kg. The velocity of recoil is

0.2 m/sec

0.1 m/sec

0.5 m/sec

0.05 m/sec

Text Solution

Verified by Experts

The correct answer is:

According to principle of conservation of linear momentum, m_{G} v_{G} = m_{B} v_{B}

\(v_{G} = \frac{m_{B} v_{B}}{m_{G}} = \frac{0.1 \times 10^{2}}{50} = 0.2 \, m/s\)
