a bullet of mass 10 gm is fired with a velocity of 150m/s from a gun of mass 4kg . calculate the recoil of the gun. why is the acceleration produced in gun is less than that of bullet .
pls help its urgent

Answer:
.
Given,
mass of bullet, m = 10g = 0.01 kg
initial velocity of bullet, u = 150 m/s
final velocity of bullet, v = 0
mass of gun, M = 4kg
initial velocity of gun, U = 0
final velocity of gun, V = ?
.
we know that,
mv + MV = mu + MU
(you probably use m1, u1 etc but I haven't used it here because it isn't possible to write in subscript here, hope u understand)
So,
putting the values,
0.01×150 + 4×V = 0.01×0 + 4×0
=> 1.5 + 4V = 0
=> 4V = -1.5
=> V = -1.5/4 = -0.375
.
therefore,
the recoil of the gun is 0.375 m/s
.
The acceleration produced in the gun is less than that of bullet because the mass of the gun is more than that of the bullet.
.
Hope this helps :)
