A cylinder of mass m and a block of wood of mass m are both released from rest at a height h on an inclined plane at the same time. The cylinder rolls down the plane without slipping due to friction. The block slides down the incline. If they both experience the same frictional force, which has more total kinetic energy when they reach the bottom?

A. The cylinder
B. The block
C. they have the same total kinetic energy when they reach the bottom
D. there is not enough information to answer this question

A

Explanation:

Because in block friction does not work hence case of cylinder has more total K.E

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.
