Suppose a 0.04-kg car traveling at 2.00 m/s can barely break an egg. what is the minimum sped a 0.08-kg car would need to have in order to break the egg?

V= 1m/s

Step by step Explanation:

1.  The car needs a certain impulse to break the egg.  The impulse is given by:

                                          I=m. ΔV

where I  is the impulse, m is the mass of the car and ΔV is the change of velocity of the car.   The impulse excerted by the car of 0.04kg is:

I=    (0.04kg)( 2m/s ) =0.08 kg.m/s

take into account that the change of velocity is taken as 2 m/s because the instruction says the car can "barely" break the egg, the word "barely" suggest us that after breaking it, the car stops, i.e., its final velocity is 0 m/s.

2. With this information we know that, to break an egg, we need an impulse of 0.08 kg.m/s at least.

Another car of 0.08kg could break the egg if this achieve an impulse of 0.08 kg.m/s.

Replacing in the equation of impulse, we can find the minimum speed:

0.08 kg.m/s = (0.08kg)(V)

V= 1m/s

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.
