Question

Explain, in terms of impulse and momen-tum, why it is advisable to place the butt of a rifle against your shoulder when first learning to shoot.

Answer 1

When held loosely, the recoil momentum of the rifle works against only the mass of the rifle, thereby producing a larger velocity and striking your shoul-der. The recoil momentum must work against the mass of the rifle and you, resulting in a smaller velocity.

Answer 2

if the rifle is not placed against shoulder, the impulsive force can possibly damage face due to it
