Answer:

101.65 m/s

Step-by-step explanation:

Step one:

Given data

m1= mass of gun.= 480kg

m2= mass of bullet. = 85kg

v1=

v2= final velocities of bullet. = 18 meters per second

m1u1+m2u2=m1v1+m2v2

u1=0; u2=0

0=m1v1+m2v2

Step two:

Recoil velocity v1= -(m1/m2)v2

v1= -(480/85)18

v1= 5.64*18

v1=101.65 m/s
