Question

A bullet of mass 10 gram is fired with a velocity of 400 metre per second from a gun of mass 4kg.what is the recoil velocity of the gun?...Please answer it?

Answer 1

solution:

[tex]m_{1}=4kg(mass of gun)\\ and m_{2}=0.010kg(mass of bullet)\\ v_2=400m/s(velocity of bullet)\\ m_1\times v_{1}=M_2\timesv_2\\ 4\times v_{1}=0.010\times400\\ v_{1}=4/4\\ v_{1}=1m/s[/tex]
