# Is it possible to reach escape velocity?

## Is it possible to reach escape velocity?

In most situations it is impractical to achieve escape velocity almost instantly, because of the acceleration implied, and also because if there is an atmosphere, the hypersonic speeds involved (on Earth a speed of 11.2 km/s, or 40,320 km/h) would cause most objects to burn up due to aerodynamic heating or be torn …

Can a railgun reach escape velocity?

Railguns can acheive a muzzle velocity of a projectile on the order of 7.5 km/s. The Earth’s escape velocity is 11.2 km/s.

### What is the highest escape velocity?

What is escape velocity?

Body Mass Escape Velocity in Miles/Hour
Ceres (largest asteroid in the asteroid belt) 1,170,000,000,000,000,000 kg 1430.78 mph
The Moon 73,600,000,000,000,000,000 kg 5320.73 mph
Earth 5,980,000,000,000,000,000,000 kg 25038.72 mph
Jupiter 715,000,000,000,000,000,000,000,000 kg 133018.2 mph

How fast do you have to go to escape Earth’s gravity?

If you want to completely escape Earth’s gravity and travel to another moon or planet, though, you need to be going even faster – at a speed of at least 7 miles per second or about 25,000 miles per hour.

#### What do black holes do in space?

A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion.

Is it illegal to make a rail gun?

As the other answers have stated: no this is not illegal in the United States.

## What is the moon’s escape velocity mph?

5,300 mph
The escape velocity at the moon is just a shade faster than that — 5,300 mph (8,530 km/h). Magnetic fields created by high electrical currents accelerate a sliding metal conductor, or armature, between two rails to launch projectiles.

Is it possible to reach the escape velocity of a black hole?

In the case of a black hole mass is large and radius keeps on decreasing therefore the escape velocity is more than speed of light. However, according to theory of relativity nothing can travel faster than speed of light(in vacuum) therefore nothing can escape a black hole.

### Which planet has lowest escape velocity?

Pluto is the smallest planet so it will have the least escape velocity….

Planet Observations Escape Velocities (km/sec) Mass Relative to Earth
Earth 11.2 1
Jupiter 63.4 317.8
Mars 5 0.11
Mercury 4.2 0.06

Can we live without gravity?

It might seem like a fantasy to float weightlessly through the air but practically, the human body would go through negative change, such as muscle and bone atrophy while living in zero gravity. Even the rivers, lakes and oceans on Earth wouldn’t stand in zero gravity, without which humans cannot survive.
