Atrapeze artist of mass m is launched horizontally toward a swing of mass m, which is at rest hanging vertically from hooks in the ceiling. the "system" consists of both the trapeze artist and the swing. during the moment when she grabs (and holds on to) the swing, what quantities are conserved, and why?

During the moment when she grabs the swing is conserved the angular momentum and the energy.

Explanation:

The external torques in a system change the momentum or:

Where dl is the change in the angular momentum, dt the change in the time and T the torque.

So, if the external torques is equal to zero, the mometum is conserved. In this case, there are not external torques in the system therefore the momentum is conserved.

On the other hand, the energy is conserved when there aren't no conservative forces in the system, like friction, so, in this case if we ignore the air resistance the energy is conserved.

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.

i don’t know what the answer is i wish i
