A 5.34g bullet leaves the muzzle of a rifle with a speed of 348 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.812 m long barrel of the rifle?

Solutions

Expert Solution

Answer:-   Force :

Explanation:-

Let,

  • : be the acceleration of the bullet
  • : be the initial velocity of the bullet
  • : be the final velocity of the bullet
  • : be the distance
  • : be the force exerted on the bullet.
  • : be the mass of the bullet.

Given:-

By Kinematic equation we have,

Initially, the bullet is at rest, therefore the initial velocity becomes zero,

This is the acceleration of the bullet.

According to the Newton's second law of motion we have,

This is the force exerted on the bullet while it is traveling down the 0.812 m long barrel of the rifle.

Show a complete derivation of the “muzzle speed” of the bullet from the ballistic pendulum. You will use conservation of energy and conservation of momentum to determine vmuzzle in terms of mB the mass of the bullet, MP the mass of the pendulum, and h the change in height of the combined pendulum/bullet mass after they stick together. This will be called the “ballistic pendulum equation”
