Let mass of the bullet be m1 = 20g = 20/1000 = 0.02 kg
mass of gun be m2 = 4.5kg
velocity of bullet be v1
= 1.08 kmph = 108/100 * 1000/3600 = 0.3 mps
recoil velocity of gun be v2 = ?
Now,
As,
v2 = -(m1v1)/m2 = -(0.02 * 0.3) / 4.5 = -0.00133333.........
mass of gun be m2 = 4.5kg
velocity of bullet be v1
= 1.08 kmph = 108/100 * 1000/3600 = 0.3 mps
recoil velocity of gun be v2 = ?
Now,
As,
