An angry mob lynches a phsical teacher after receiving their grades. they throw the physics teacher off a tall building . they throw the physics teacher straight down with a velocity of 20m/s. the teacher falls for 30 seconds before landing on a stack of empty card board boxes . how high was he thrown from?

5010 m

Explanation:

The vertical position of the teacher at time t can be found by using the equation:

where

h is the initial height

is the initial velocity (negative since it's downward)

is the acceleration of gravity

t is the time

The teacher reaches the ground when y = 0, so the equation becomes

Substituting t = 30 s, we find the initial height:

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
