Two bicyclists ride towards each other along a long straight road, each with a constant speed of 10 km/h. When they are 20 km apart, a bee begins flying from the front of one bicycle towards the other at 30 km/h. When the bee reaches the other bicycle, it immediately turns around and starts flying back towards the original bicycle at the same speed. This repeats until the bikes crash into each other and the bee is squished. A. How many trips does the bee travel before it gets squished?

B. For how long will the bee survive?

C. What is the total distance the bee will travel?

Explanation:

A )

As the two bicycles come closer , the time period of oscillation of bee to oscillate between the two is gradually reduced . It is akin to a pendulum with gradually decreasing amplitude . It will be infinite number of trips the bee will travel before it gets squished .

B )

The bee will survive until the two bicyclists meet each other .

time of their meeting = distance between them / their relative velocity

= 20 / ( 10 + 10 )

= 1 hour .

C )

Total distance travelled by bee during 1 hour

= time x speed of bee

= 1 x 30 km/h

= 30 km .

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.

are there options? cause you ain’t. real specific
