Drew bill and kieth push horizontally on chuck (100kg). drew and bill each push to the right with force 2f and keith pushes to the left with a force of f. chuck moves and accelerates to the right at 2 m/s^2 across the floor where coefficient of friction is 0.5. what is the magnitude of keith’s push?

The magnitude of Keith’s push is 230 N

Explanation:

Given:

Mass of chuck, kg

Acceleration of the chuck, m/s².

Coefficient of friction,

Frictional force acts to left as motion is to right.

Frictional force is given as:

as net force in vertical direction is zero.

Total force to the right,

Total force to the left,

Net force acting on the chuck,

According to Newton's second law,

Keith applies a force of towards left.

Therefore, the magnitude of Keith’s push is 230 N.

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.
