Plot the solutions with initial values y = 0 and v = b where b is 0.5, 1.0, 1.5, and 2. You can either left click onto the appropriate points in the pplane "Display" window or use the "keyboard input" option in the "Solutions" pull down menu of the "Display" window. What is the maximum height of the object (in miles) in each case where there is a finite maximum ? (Recall that 4000y = x.) In the cases where there is no maximum, approximate the limiting value of v as s −→ [infinity]. (This is the terminal velocity). What is the terminal velocity in miles/sec?

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.

none, its a machine

need to see circuit to get time constant
