Aspring of equilibrium length l1 and spring constant k1 hangs from the ceiling. mass m1 is suspended from its lower end. then a second spring, with equilibrium length l2 and spring constant k2, is hung from the bottom of m1. mass m2 is suspended from this second spring. how far is m2 below the ceiling?

The total distance of m₂ from the ceiling is

The given parameters;

The extension of the first spring due to mass m₁ and m₂ is calculated as;

The extension of the second spring due to mass (m₂) is calculated as;

The total distance of m₂ from the ceiling is calculated as follows;

Thus, the total distance of m₂ from the ceiling is

Explanation:

For first spring the total extension is given as

here net force is due to weight of both masses

so extension of first spring is

now similarly the extension in second spring is only due to the weight of mass m2

so here we will have

so the total distance from the ceiling for mass m2 is given as

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.
