Ajuggler is performing her act using several balls. she throws the balls up at an initial height of 4 feet, with a speed of 15 feet per second. if the juggler doesn't catch one of the balls, about how long does it take the ball to hit the floor?

hint: use h(t) = _16t2 + vt + s.

7.52 seconds
1.15 seconds
0.47 second
0.22 second

The correct answer between all the choices given is the second choice, which is 1.15 seconds. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

The ball will take 1.15 seconds to hit the floor.

Explanation:

It is given that,

A juggler is performing her act using several balls. The height as a function of time is given by :

.............(1)

where

v is the speed of the ball

s is initial height

t is time taken

Putting h(t) = 0 and solving equation (1)

On solving above equation using graphing calculator and solving for t we get, t = 1.154 seconds

Hence, the correct option is (b) " 1.15 seconds ".

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.
