Find the speed (in m/s) needed to escape from the solar system starting from the surface of Neptune. Assume there are no other bodies involved, and do not account for the fact that Neptune is moving in its orbit.

The speed needed to escape from the solar system starting from the surface of Neptune is approximately 23557.615 meters per second.

Explanation:

The escape speed needed to escape from the gravitational influence of a planet (), measured in meters per second, is derived from Newton's Law of Gravitation and Principle of Energy Conservation and defined by the following formula:

(1)

Where:

- Gravitational constant, measured in cubic meters per kilogram-square second.

- Mass of Neptune, measured in kilograms.

- Radius from the center to surface, measured in kilograms.

If we know that , and , then the escape speed needed is:

The speed needed to escape from the solar system starting from the surface of Neptune is approximately 23557.615 meters per second.

sleep paralysis is a parasomnia, events associated with sleep.

sleep paralysis happens when you are in the middle of waking up or falling asleep. it is the feeling of being conscious but unable to move. it definitely involves hallucinations.

i had a friend that had sleep paralysis and he told me a story one time where he was laying in bed and he couldn't move his body no matter how hard he tried and there was someone standing in the corner of his room coming towards him. he couldn't move and you can't "wake up" because you are already conscious. sometimes sleep paralysis can be triggered by frequent waking up during the night based off of multiple trips to the bathroom, or if you had ever been abused, sleep paralysis can start happening from things like that.
