A bullet weighing 50 grams leaves the gun with a velocity of 30m/s. The ratio of momentum of the bullet to the gun is what?

Expert Answer:

 the momentum of the bullet = 0.05 kg x 30 m/s = 1.5 kgm/s
 
By newtons third law
 
the bullet will exert equal and opposite reaction on gun 
 
the momentum of gun= -1.5 kgm/s
 

the ratio of the momentum of the bullet to the gun = 1.5/-1.5= -1
