What would happen if you fired a gun on a train moving as fast as a bullet?

If you shoot the bullet off the back of the train, the bullet will still be moving away from you and the gun at 1,000 mph, but now the speed of the train will subtract from the speed of the bullet. Relative to the ground, the bullet will not be moving at all, and it will drop straight to the ground.

What term is used to describe the direction that a bullet is traveling?

The trajectory of a bullet is the path of flight it follows from being fired to reaching its target. In cases of shootings that claim a victim as their target, the forensic specialist will want to try to work out the trajectory of the bullet as part of the crime scene reconstruction .

What can change the direction of a bullet?

Teledyne Scientific and Imaging’s Extreme Accuracy Tasked Ordnance (EXACTO) program, which is being developed with funding from DARPA, has developed a self-steering bullet. Intended for long-distance shots, the EXACTO bullet is able to change course in order to strike moving targets.

Why a bullet fired hits the ground at the same time as a bullet dropped from the same height?

Since gravitational acceleration acts on both a horizontally launched bullet and a vertically dropped bullet in free fall, they both will reach the ground at the same time as their vertical initial velocity is zero.

Is a bullet faster than the train?

Relative Velocity We have to assume, for this article, that the bullet in question has the same velocity as the train (although in reality, most bullets travel faster than a train).

Can bullets change direction in flight?

It’s always easier to hit a bull’s-eye when your bullet can change direction in midair. The Defense Advanced Research Projects Agency (DARPA) has developed the technology for a self-steering bullet meant for long-distance shots, that has the capability to change direction during flight.

Is there a smart bullet?

In February, the “smart bullets” – . 50-caliber projectiles equipped with optical sensors – passed their most successful round of live-fire tests to date, according to the Defense Advanced Research Projects Agency, or DARPA.

Which will hit the ground first an object dropped or shot?

That is the only force that causes the ball to drop. The hand can no longer impart any force, as the ball has left it. As gravity is the only force in both cases, both balls will hit the ground at the same time.

Does gravity affect a bullet?

In fact, the apparent acceleration towards the Earth g will be 0.068 m/s2 less than for the bullet that is dropped straight down: the flying bullet will appear “lighter”. Since the time to fall scales with √2hg, a change of 2 parts in 300 in gravity results in the bullet falling more slowly by about 1 part in 300.
