A60.0 kg astronaut is freely floating in space and pushes on a freely floating 120.0 kg spacecraft with a force of 30.0 n for 1.50 s. (a) compare the forces exerted on the astronaut and the spacecraft, and (b) compare the acceleration of the astronaut to the acceleration of the spacecraft

Explanation:

mass of astronaut, m = 60 kg

mass of space craft, M = 120 kg

t = 1.5 s

Force on space craft = 30 N

(a) According to Newton's third law

Force on spacecraft by the astronaut = Force on astronaut by the space craft

Force on astronaut by the space craft  = 30 N

(b) According to Newton's second law

Force  = mass x acceleration

Let a be the acceleration of the astronaut

30 = 60 x a

a = 0.5 m/s^2

Let A be the acceleration of the spacecraft

30 = 120 x A

a = 0.25 m/s^2

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.

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
