Ahorizontal force of 110.9n is applied to a sled producing an acceleration of 59.7 m/s^2. calculate the mass of the sled. a) 18.223kg;
b) 1.858kg;
c) 0.538kg;
d) 674.896kg;

B) 1.858kg

Explanation:

Hello! to solve this exercise you must be clear about Newton's second law, this is the physical law of the movement that explains that if we apply a certain force to an object that has mass this will produce a movement with certain acceleration, for this reason Newton developed the following formula

F=ma

where

F=force=110.9N

a=aceleration=59.7m/s^2

m=mass

solving for m

the mass of the sled is 1.858Kg

the force required to move the cart is divided by three or 33.33 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.
