A projectile is shot from the edge of a cliff 170 m above ground with an initial speed of 75.0 m/s at an angle of 24° below the horizontal. How much time does it take the projectile to hit the ground?

It will take 6.1seconds for the projectile to hit the ground.

Explanation:

In projectile, the time taken by an object to spend in air is its time if flight.

Time of flight = 2Usin(theta)/g

where u is the initial velocity = 75m/s, theta = 24°, g = 10m/s²

Time of flight = 2(75)sin24°/10

Time of flight = 150sin24°/10

Time of fight = 6.1seconds.

This means that it will take 6.1seconds for the projectile to hit the ground.

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.
