A hockey puck with a mass of 0.17 kg is traveling to the right along the ice at 15 m/s. it strikes a second hockey puck with a mass 0.11 kg. the first hockey puck comes to rest after the collision. What is the velocity of the second hockey puck after the collision? ( Round your answer to the nearest integer.)

Explanation:

Given

-- Initial Velocity of the first

-- Initial Velocity of the second

-- Final Velocity of the first

Required

Determine the final velocity of the second hockey puck ()

This question illustrates law of conservation of momentum and it'll be solved using the following formula:

---- law of conservation of momentum

Substitute in the right values

Solve for v2

Hence, the final velocity of the second hockey puck is 23.182m/s

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.

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6
