For example, chickens. Tons of chickens running around laying lots of eggs and not so many roosters. It seems that this phenomenon is confined to animals that produce yummy eats for all of us, so what, if any method is used to control the sex of said animals? Cows too. All these dairy cows giving milk. Where are their male counterparts?

I think it is Mars that I heard could be lived on. But since Mars is probably 35 million miles away from Earth, how long would that take in years for people to actually get there? And isnt it true that people cant survive in space for more than 3 years?

A gun fires a bullet of mass 26 grams out of a barrel 32 cm long. The gun is attached to a spring. From the recoil of the spring and the masses of the gun and the spring we determine that the gun recoiled with a total momentum of 6.2 kg m/s.

* How do I find the velocity of the bullet as it exits the barrel?
* What was the avg force exerted on the bullet as it accelerated along the length of the barrel?
* What average force would be felt by the individual holding the gun for the time the bullet accelerates along the length of the barrel?
