When you see a traffic light turn red, you apply the brakes until you come to a stop. your initial speed was 13 m/s. assume constant deceleration. suppose the car comes to rest in 38 m. how much time does it take?

time is 5.85 sec

Explanation:

given data

speed u = 13 m/s

distance s = 38 m

to find out

How much time taken

solution

we know that formula for find time t

v = u + at   1

so first we find a

we will apply here formula to find a that is

v² - u² = 2×a×s    2

here we have given u and s and we know v = 0

so we find here a

0² - 13² = 2×a×38

-169 = 76 a

a = - 2.223

so from equation 1

0 = 13 - 2.223 × t  

t = 13 / 2.223 = 5.85

time is 5.85 sec

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

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.
