How much kinetic energy does a 1000 kg car have when it is traveling at 30m S?

How much kinetic energy does a 1000 kg car have when it is traveling at 30m S?

Units: Joules (J) Page 16 Example #2: What is the Kinetic Energy of a 1,000 kg car moving at 30 m/s? KE = 450,000 J Page 17 Example #3: What is the Kinetic Energy of a 20,000 kg freight car moving at 25 m/s?

How do I calculate kinetic energy?

In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.

What is the kinetic energy of a 45 kg object moving at 13 sec?

Answer: The Kinetic Energy of the object is 3802.5 J.

How does kinetic energy kill you?

The fact is that whether it is the kinetic energy or the momentum of it, the bullet will kill you. No need to mention the kinetic energy will kill you because your body tissue is trying to stop that bullet velocity to zero in a very short time span with a very small area of contact.

Does a bullet hit harder than a punch?

Very easily, the amount of force behind a bullet is simply directly equal and opposite to the recoil force exerted on the weapon firing it. Bullets often contain less kinetic energy in them than a punch does, they are simply far more efficient and precise at delivering that energy.

Do Navy SEALs use hollow points?

Modern hollow points stay as one piece and unload most if not all their energy on the first target they hit. That is why police use only hollow points in pistols to avoid hurting the public if forced to shoot a criminal. The 1911 was pretty unpopular with SEALs. Too heavy and it didn’t carry a lot of bullets.

What pistol do Navy SEALs carry?

P226 MK25

Why can’t the military use hollow points?

Hollow points have been outlawed for military use under the Geneva Convention. The reason cited is because it causes excessive pain and suffering.

Why do cops use hollow point bullets?

Bullet fragments from a hollow point can bounce off bones and spread through the victim’s organs and flesh to make survival much less likely. The most common argument for why police use hollow points over full metal jackets is that hollow points minimize the risk of an unintended target being hit.

What sidearm does the Secret Service use?
