Agrinding wheel is spinning with an initial angular velocity +ω0. when its motor is turned off at t=0, it begins to slow down with an angular acceleration −α. derive an expression for the number of revolutions that the wheel will rotate through before coming to rest. express your answer in terms of the variables ω0 and α, and the constant π.

Explanation:

Given

initial angular velocity is

when motor is turned of it started decelerating with  angular acceleration

angle turned before coming to halt

here final angular velocity is zero

No of revolutions will be

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 don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.
