Arocket initially at rest accelerates at a rate of 99.0 meters/second2. calculate the distance covered by the rocket if it attains a final velocity of 445 meters/second after 4.50 seconds.
a) 2.50 × 102 meters
b) 1.00 × 103 meters
c) 5.05 × 102 meters
d) 2.00 × 103 meters
e) 1.00 × 102 meters

The correct answer is option b.

Explanation: We are given that the rocket is at rest initially final velocity is 445m/s.

The acceleration of the rocket is

To calculate the distance of rocket, we use third equation of motion, which is:

where, v = final velocity = 445m/s

u = initial velocity = 0m/s

a = acceleration =

s = distance = ? m

Putting values in above equation, we get:

the answere is B

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.
