Question

A bullet of mass 20g is fired fron a gun of mass 100kg with a velocity 80 m/s.Find the recoil velocity of the gun​

Answer 1

Answer:

4×10^5 metre per second.

Explanation:

First, we have to change grams in Kg .

Apply formula m1v1= m2v2

Put the values, and you will find the recoil velocity of the gun.

Answer 2

Explanation:

Mass of gun, m=100kg

Mass of bullet l, m=20g=0.02kg

Velocity of bullet=80m/s

Let reciol velocity of gun be v m/s

Since fnet (horizontal) =0

So, delta (P) =0

0.02×80=100v

=1.6/100

V=0.016m/s

Answer :

V=0.016m/s
