Question

A shell of mass 0.01 kg fired by a gun of mass
10 kg. If the muzzle speed of the shell is
50 ms, what is the recoil speed of the gun?
​pls answer fasttttt

Answer 1

Mass of gun = 5.0 kg

Mass of bullet = 0.01 kg

Velocity of bullet (v) = 250 m/s

Initial momentum of the system Pi = 0

Applying the conservation of linear momentum Pf = Pi

M × V+M × V = 0

5×V+0.01×250 =0

V = -0.5 m/s
