Answer:

35/80 => 7/80

Explanation:

Let the recoil velocity of gun after firing is 'V'.

Mass of the bullet is 50g i.e 1/20 kg (m) and mass of gun is 40kg (M).

Velocity of bullet is 35m/s(v)

Velocity of gun and bullet before firing is 0.

.

Conserving Linear momentum

M.0 + m.0 = m.v + M(-V)

40.V = (1/20)35

V = 35/80 m/s

Negative if your direction is wrong.
