A 14000 kg tank moving at 9 m/s is brought to a halt in 2.5 s by a reinforced-steel tank barrier. What magnitude of the impulse was imparted to the tank

Answer

The value is  

Explanation

From the question we are told that

  The mass of the tank is  

   The speed is  

   The duration taken to bring it to a stop is  

Generally the impulse that was imparted on the tank is mathematically represented as

Generally the v is the final velocity of the tank which is  v = 0 m/s , given that it was brought to rest

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.

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.
