Aperson throws a balloon straight down above level ground. the balloon bounces back up into the air. drag force is significant when the balloon is moving. verbally describe a free-body diagram for the balloon for each of the following times (you must include the force type, source, receiver, and direction for each force; relative magnitudes, when known, must be clear):

the balloon is being thrown down and is speeding up.
the balloon is in the air on its way down and is moving at constant speed.
the balloon has hit the ground and is instantaneously at rest as it reverses direction.
the balloon is in the air on its way back up and slowing down.
the balloon is in the air and is instantaneously at rest at the peak of its trajectory.

Explanation:

   a) Balloon is being thrown down and is speeding up;

           mg >

  b) Balloon is in the air on its way down and moving with constant speed.

            =mg

  c) The Balloon is on the ground and rest instantaneously

           mg = Normal

  d) Balloon is moving slowly downward;

   e) Because, at the peak of trajectory drag force  is 0.

             Drag force = 0

the independent variable, the one that is intentionally manipulated, is whether or not the car hits the barrier.

the dependent variable, the one that you measure the response in, is the distance that the washers travel.

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.
