A student throws a 9 gram of gum is thrown across the physics lab from a distance of 2.1 m. When the gum has a horizontal velocity of v0 it connects with a mass on the end of 1.58 kg simple pendulum which is initially at rest. The pendulum has a length of L of 0.76 m. The gum sticks to the pendulum mass and swings backwards to gain a vertical height of 11.3 cm. 1) What is initial velocity of the wad of gum?

vmax = m/sec

2) How long does it take the pendulum (and the gum) to come to rest for the first time?

t = Seconds

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.

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
