Question

A 0.22LR-caliber bullet like that mentioned in Example 7.10 is fired into a door made of a single thickness of 1-inch pine boards. How fast would the bullet be traveling after it penetrated through the door?

a) 343 m/s
b) 788 m/s
c) 521 m/s
d) 657 m/s

Answer 1

The speed of the 0.22LR-caliber bullet after penetrating the door cannot be determined without additional information.

Step-by-step explanation:

To calculate the speed of the bullet after penetrating the door, specific details such as the initial velocity of the bullet, its mass, and the resistance offered by the door would be required. The problem, as presented, lacks these essential parameters for a quantitative analysis.

Physics problems involving projectile motion and penetration typically involve variables such as initial velocity, mass, and the material properties of the objects involved. Without this crucial information, it is not possible to accurately calculate the bullet's speed after passing through the door.

In summary, the question provides insufficient data to determine the speed of the bullet after it penetrates the door. The absence of key variables required for a physics calculation prevents a conclusive answer to be chosen from the given options.
