Which will be more effective in knocking a bear down rubber bullet or lead bullet of same momentum?

Answer 1

Since we know that according to the Newton second law of motion we have the equation as,

F= ∆P/∆t

So if the momentum is same then F is inversely related to time.

Since lead bullet will obviously penetrate and will take more time so will have relatively less force will be applied to knock the bear down.

But on the other hand the rubber bullet will just strike the body of the bear for little time instead of getting penetrated ,so it will deliver more force.

Thanks

Answer 2

I would go with a lead bullet. The elasticity of the rubber would absorb more the energy on impact (turning into wasted heat) but the lead bullet is less likely to deform and therefor, more likely to penetrate the bear skin.

Both would injure the bear with hydrostatic shock, but the lead bullet would be more likely to create a wound channel, which would speed exsanguination. Answer: The question is not answerable without more information. The key word is momentum. Since momentum is mass x velocity, if they both have the same momentum (and presumably the same calibre), then the less massive rubber bullet will strike with a correspondingly higher velocity. The lead bullet would strike with lower velocity since it has the greater mass, so the answer depends on how much momentum they share. It will also depend on the shape of the bullets, since a pointed bullet--even one of rubber--will penetrate further than a flat or rounded one.

Answer 3

rubber bullet is preffered as mass of rubber bullet is less than that of lead bullet so velocity of rubber bullet will be more than lead so rubber bullet will take less time to hit bear as time and impulsive force have inverse relation so rubber bullet will hurt more

if knocking down a bear means to kill than lead bullet is preffered as it can penetrates through the body of bear and if knocking down a bear means to fall a bear than rubber bullet is preffered

Addendum:

Consider using a ,308 caliber or larger, soft tip, 180 gr. Hunting round. Shooting a bear with a rubber bullet may knock it down, but it will tick off the animal too. Unless you enjoy the idea of being mauled, shoot to kill.

Answer 4

a lead bullet will be used because it hearts the bear more as it applies large impulsive force on bear
