If I shoot a bullet straight up in the air and it returns to earth at my feet, at what point was the bullet at its highest velocity?

The highest velocity is when the bullet just leaves the gun. From then on the air friction and gravity slow it down. If the gun is above the ground you could argue it falls further that it ascended. However, one would have to take the terminal velocity into account. That would be a complicated calculation.
