A ball is dropped from 215m. How long will it take to reach the ground? Use 9.8 m/s^2 for g. Round answer to 2 places after the decimal

The time is  

Explanation:

From the question we are told that

   The height of the platform where the ball was dropped from is s  =  215 m

   The acceleration due to gravity is  

Generally from kinematic equations

Here u is the initial velocity of the ball and the value is  u = 0 m/s given that the ball was at rest before it was dropped

So

=>  

=>  

=>  

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.
