Glaunch to impact a ball, initially at rest and 1 meter above ground, is launched upward with a 500n force acting for 0.02 seconds. the ball flies vertically upward to a maximum height and falls back, sinking into the soft ground a distance of 2.0 cm. calculate the velocity after 0.01 seconds of force is applied, the maximum height if the force terminated when the ball was 2m above ground, the velocity of impact when it reached the ground and the average force exerted by the ground on the ball.

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.
