Why does a bullet shot from a gun go well inside a wooden block but a bullet thrown by hand does not?

The reason is that a bullet shot from a gun is traveling so much faster than any person could possibly throw it. Also, the increased velocity of the bullet is more relevant than it may seem because the kinetic energy of any object in motion is 1/2•mv2 where m is the mass of the object and v is its velocity. If the velocity of an object doubles, then its energy increases by a factor of four, not two.
The best pitchers in professional Baseball can throw a ball at about 100 MPH. Let's assume that a person can throw a bullet at 100 MPH. A bullet shot from a handgun firing the slowest cartridge commercially available travels at over 400 MPH. This means that the energy of the speeding bullet fired from a handgun is more than 16 times greater than the same bullet thrown at 100 MPH.
To summarize, a bullet thrown at even 100 MPH is not going fast enough, and as a result, does not possess nearly enough energy to penetrate a wooden block.
