Aman pushes on a 12kg object for 10 seconds. it moves 8 m to the right while he is pushing it.
a. calculate the acceleration of the mass
b. now use f=ma to calculate the magnitude of the man's force.
c. if the surface is frictionless, how does v3 compare to v2? why?
d. if the surface has friction, how does v3 compare to v2? why?

Explanation:

So for part a you know:

mass: irrelevant for first part

time

distance traveled

And i believe you can assume it starts at rest

So use x= v0t + 1/2at^2

8= 0(10) +1/2a(10)^2

So simplifying the first part of the equation becomes zero and the next part become 50a

Leaving you with 8=0+50a

so a =8/50

Part B

use f=ma to solve the force

f= (12kg) * (8/50)= 1.92

Par c and d im not sure what you mean by v2 and v3

Hope this at least helped with the first two parts

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.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
