Question

4. A bullet of mass 0.03kg is shot from a gun with a velocity 300 m/s .Find the mass of the gun

if the recoil velocity is 0.6m/s?​

Answer 1

Explanation:

Let the mass of gun be M

Conserving Linear momentum in horizontal direction,

0= MV +mv

0.03 ×300 +M × (-0.6)

M = 0.03×300/0.6 = 15
