A gun fires a bullet horizontally with a velocity of 90 m/s from a tower. Neglecting air resistance, how far will the bullet travel horizontally in 4 seconds?

The distance covered along the horizontal axis is

The distance covered along the vertical  axis is  

Explanation:

From the question we are told that  

    The horizontal velocity is  

     The time considered is  

Generally the distance which the bullet will cover in the horizontal direction for the given time is  mathematically represented as

Here a is the acceleration along the horizontal direction and the value is  

So

=>  

Generally the distance which the bullet will cover in the vertical  direction for the given time is  mathematically represented as

Here   is the initial  velocity of the bullet along the vertical axis and the value is  

=>          

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.
