Question

from a rifle of mass 4 kg A bullet of mass 50g is fired with an initial velocity of 35 metre per second calculate the initial recoil velocity of the rifle. explain this with answer​

Answer 1

Explanation:

m1=0.05

m2=4

u1=u2=0

v1=35

to find v2

m1u1+m2u2=m1v1+m2v2

0=0.05*35+4(v2)

1.75=4(v2)

v2=1.75/4

v2=0.4375m/s
