Question

$\huge\boxed{♤Question♤}$

From a rifle of mass 5kg, a bullet of mass 50gram is fired with an initial velocity of 50m/s. Calculate the initial recoil velocity of the rifle.​

Answer 1

Answer:

m1= 5kg

m2= 50g = 50×10^-3kg

u2= 50m/s

By using m1u1 + m2u2 = 0

u1= -50×10^-3 ×50 divided by 5

= -0.5 m/s

Negative sign here indicates that the gun moves in the opposite direction (recoils)
