Asmall toy school bus rear-ends a big toy school bus initially at rest. the bigger bus is several times heavier than the smaller one. which of the following statements are true if the collision is elastic?
true / false / maybe.
1. the two busses continue together at the same speed.
2. mechanical energy is conserved.
3. the small bus exerts the same amount of force on the big bus as vice versa.
4. momentum is conserved.
5. the small bus will go backwards.

Explanation:

1 . The two busses continue together at the same speed.

FALSE STATEMENT .

The small bus will have twice the velocity of bigger bus  velocity in the same direction . The bigger bus will continue with the same velocity .

2. Mechanical energy is conserved

TRUE STATEMENT.

3  The small bus exerts the same amount of force on the big bus as vice versa.

TRUE STATEMENT.

4.Momentum is conserved

TRUE STATEMENT.

5.The small bus will go backwards

FALSE STATEMENT .

The small bus will have twice the velocity of bigger bus  velocity in the same direction .

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.

b.

hope this : )
