Amass of 1.03 kilograms is placed on a horizontal frictionless surface against an uncompressed spring with spring constant 861.1 n/m. the mass is pushed against the spring until the spring is compressed a distance 0.36 m and then released. how high (vertically) in m does the mass rise from the original height before it stops (momentarily).

5.522 m

Explanation:

Data provided:

Mass, m = 1.03 kg

spring constant, k = 861.1 N/m

Distance by which the spring is compressed, x = 0.36

Thus,

the energy stored in the spring =

on substituting the values, we get

the energy stored in the spring =  

now,

by the conservation of energy, we have

Potential energy gained by the mass =  Energy gained by the spring

or

mgh =

where,

g is the acceleration due to the gravity

h is the maximum height reached by the mass before falling

on substituting the values in the above relation, we get

1.03 × 9.81 × h =

or

h = 5.522 m

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.

i think the answer would be reserve.
