What is recoil velocity of a gun derive its formula?

The velocity with which it recoils is called as Recoil Velocity. Derivation For recoil velocity of Gun: mu1+Mu2=0If v1 and v2 are the final velcoities of bullet and gun receptively after firing. Then According to law of conservation of momentum. Total momentum before recoil = Total momentum after recoil.

Why can a small mass such as a bullet?

Why can a small mass such as a bullet kill a person when fired from a gun? Answer: It is so because even if the mass of the bullet is small, it moves out of the gun with a very high velocity, due to which the momentum produced is high (p = mv). This high momentum of the bullet kills a person.

How much velocity does a bullet lose when it passes through planks?

A bullet loses 1/6 of its velocity in passing through a plank. What is the number of planks required to stop the bullet? – Quora A bullet loses 1/6 of its velocity in passing through a plank. What is the number of planks required to stop the bullet?

How many blocks does it take to stop a bullet?

A bullet loses 1/10th of its velocity when it passes through a wooden block. How many such blocks are required to stop the bullet? An infinite number. n blocks reduces the velocity to 0.9 n times the original. One thousand blocks to 1.75 x 10 − 46 times the original velocity.

What happens to the velocity of a car after 7 blocks?

After 7 blocks, the velocity will bw reduced to about 1/2 ofvthe initial velocity. After 14 blocks to 1/4. After 70 bolcks to 1/1000. If it started with 1000 m/s it will still have a velocity of 1m/s. After 140 blocks it will move with about 1 mm/s.

What happens when you lose a 20th of velocity?

Losing a 20th of the velocity means losing a 20th of the momentum. When the bullet hits the next plank, it will have be moving more slowly such that the force will have longer to act on the bullet (again) but now the force will be reduced by exactly the same amount as the time is lengthened.
