A block with a mass of 3.7 kg slides with a speed of 2.2 m/s on a frictionless surface. The block runs into a stationary spring with an energy of 980 J and compresses it a certain distance before it comes to rest. If the spring has a spring constant of 3200 N/m, what distance was the spring compressed by the block?

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.
