A bullet of mass $0 .1 kg$ is fired with a speed of $100 m s^{- 1}$ , the mass of gun is $50 kg$ . The velocity of recoil is

Options:

Answer:

Solution:

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

$v_{G} = \frac{m_{B} v_{B}}{m_{G}} = \frac{0.1 \times 1 0^{2}}{50} = 0 .2 m s^{- 1}$
