Question

A bullet of mass 10g is horizontally fired with a velocity of 100m/s from a gum of mass 10 kg. The gun will move backward with linear momentum

Answer 1

Heya

Here is ur ans

Momentum=mass*Velocity


Momemtum before gun is fired =momentum of gun after firing +momentum of bullet firing


100g=0.1kg

By conservation of momentum

(10x0.1kg)*0m/s

10kg * Vm/s +(0.1Kg *100m/s

0=10V +10

V= -1m/s

Answer 2

According to conservation of momentum

Momentum of system =momentum of gun + momentum of bullet

0= momentum of gun + 0.01•100

0=momentum of gun + 1kgm/s

-momentum of gun=1kgm/s

Momentum of gun =-1kgm/s
