A ball with a mass of 1.1 kg lies on the floor, a trolley with a mass of 0.60 kg stands on a horizontal table and a weight with a mass of 2.0 kg hangs in the wire according to the figure below. It is 0.3 m from the lowest point of the weight and the floor. Both the ball and the weight are attached to each other via wire that goes through the frictionless pulleys. When the weight falls down, the ball will be lifted and the trolley will move to the left. When the weight hits the floor, it stops, but the cart and ball continue their movement for a short while longer. How high will the ball reach the highest? Ignore friction.

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.
