Although you didn't state it explicitly in your question, we will assume the bullet fired from the rifle starts out three feet off the ground, not at shoulder height.
Assuming that, the bullets will strike the ground at nearly the same time!! For many people that is a counter-intuitive answer.
Orthogonal forces -- that is, forces at right angles to each other -- have no effect on each other. When a bullet is fired from a gun, the force due to gravity works at right angles to the bullet's horizontal motion. The bullet's horizontal motion and any forces acting on the bullet in the horizontal direction have no effect on the motion of, or the forces acting on, the bullet in the vertical direction.
When the bullet leaves the end of the muzzle of the gun, gravitational forces will start to act on the bullet immediately. The bullet will accelerate toward the ground at 9.8 meters per second squared (32.2 feet per second squared), just like any object that is dropped and falling freely.
At this point you might think they would strike the ground simultaneously. However, drag forces caused by the bullet exceeding terminal velocity would cause a lift. Similar to the principle upon which plane flight is based. This would cause the fired bullet to stay airborne slightly longer than the dropped bullet.
The dropped bullet will strike the ground in about 432 milliseconds (0.432 second).
The fired bullet will land shortly after.
(Except the bullet would go far beyond an empty football field, unless it hit a wall at the end of it or something...)

Will a bullet travel the same distance straight up that it would horizontally?
No. The horizontal distance depends on how close the the ground the gun is. From the firing position, a bullet dropped to the ground will strike the ground in the same time as a bullet shot horizontally forward.

A typical football helmet is not bullet proof but someone could create a bullet proof football helmet.
What effect does rifleing in the barrel of a gun have?
It makes the bullet spin when it is fired- much the same way a football spins in flight. The helps the bullet travel in a straight line, improving the accuracy of the gun.
Does a bullet fly straight?
No.
What is th purpose of rifling a gun barrel?
Rifling a gun barrel causes the bullet to spin when it comes out. This makes the bullet fly more straight and greatly improves accuracy. Much like a spinning football spirals.
Can a 40 bullet fit 32 gun?
If you mean a .40 caliber bullet in a .32 caliber gun- no. The bullet would be 8 thousandths of inch too large to fit in the gun. Caliber refers to the diameter of the bullet, so a .40 caliber bullet is ABOUT .40 inches across, and a .32 bullet ABOUT .32 inches across.
Where can candidates benefit from the popularity of another candidate?
One term is "bullet voting", because the voter goes straight down the line of candidates just like a bullet from a gun. Another term is "line voting", which comes from the same concept but also has the connotation of voting the entire line of candidates.
Does the 50 caliber machine gun have a spiral barrel?
The barrel is straight. However, there are spiral grooves cut on the inside of the barrels. These spiral grooves, called rifling, make the bullet spin when it is fired. Just as a thrown football spins for an accurate throw, the spinning bullet makes for an accurate shot.
Will the bullet tumble if you hold the gun sideways?
No. It will still fly straight.
Can a bullet be shot down with another bullet?
If you have incredible aim and like lightening fast reflexes, then i guess its possible, but i would say its pretty much impossible, or you would have to get like 1 and 1,000,000,000,000,000,000,000,000 lucky to stop a bullet with another bullet
Why does a bullet spin?
The answer has two parts - 1. Why do you want it to spin: It allows the bullet to be more accurate and travel further. The bullet spins for the same reason that football players spin a football when they throw it. 2. Why does it spin (How do you make it spin): Inside the barrel are grooves (rifling) that catch part of the lead of the bullet and spin it like bolt spins when you put it into a nut.
If the bore of the gun is pointed straight at the can under what conditions will the bullet hit the tin can?
