Bullet Plastic Velocity

In summary, the factors that affect bullet velocity after penetrating plastic include the type and thickness of the plastic, the type and caliber of the bullet, and the initial velocity of the bullet. The type of plastic can either slow down or fragment the bullet, depending on its hardness. The angle at which the bullet hits the plastic can also impact its velocity, with perpendicular impacts resulting in the least loss. While it is possible for a bullet to maintain its velocity after penetrating plastic, it is more likely to lose velocity if the plastic is harder or the bullet is traveling at a higher speed. Studying bullet velocity after penetrating plastic can have practical applications in ballistics, materials science, and forensics, and can also inform the development of new bulletproof

Hi, I'm doing a project where I need to find the velocity after penetrating a certain thickness of polycarbonate. What equations do I use to find this. Thanks

1. What factors affect bullet velocity after penetrating plastic?

The primary factors that affect bullet velocity after penetrating plastic include the type and thickness of the plastic, the type and caliber of the bullet, and the initial velocity of the bullet before it hits the plastic.

2. How does the type of plastic affect bullet velocity?

The type of plastic can affect bullet velocity by either slowing down or fragmenting the bullet. Harder plastics, such as polycarbonate, can cause the bullet to fragment and lose velocity, while softer plastics, such as polyethylene, can slow down the bullet but allow it to maintain its shape.

3. Does the angle at which the bullet hits the plastic affect velocity?

Yes, the angle at which the bullet hits the plastic can greatly affect its velocity. A perpendicular impact will result in the least amount of velocity loss, while an angled impact will cause the bullet to lose more velocity as it travels through the plastic.

4. Can a bullet maintain its velocity after penetrating plastic?

It is possible for a bullet to maintain its velocity after penetrating plastic, but this depends on the type of plastic and the speed and caliber of the bullet. Harder plastics and higher velocity bullets are more likely to cause the bullet to fragment and lose velocity.

5. What are some potential applications of studying bullet velocity after penetrating plastic?

Studying bullet velocity after penetrating plastic can have practical applications in fields such as ballistics, materials science, and forensics. This research can also inform the development of new bulletproof materials and help improve the design and effectiveness of body armor.
