Abullet is fired straight up from a gun with a muzzle velocity of 136 m/s. neglecting air resistance, what will be its displacement after 1.3 s? the acceleration of gravity is 9.8 m/s 2 . answer in units of m.

Explanation:

Given that,

Speed with which the bullet is fired, u = 136 m/s

Time, t = 1.3 s

We need to find the displacement of the bullet after 1.3 seconds. It can be calculated using second equation of motion as :

Here, a = -g

s = 168.51 meters

So, the displacement of the bullet after 1.3 seconds is 168.51 meters. Hence, this is the required solution.

explanation:

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.
