Answer 3

all of it, math is not my strong subject at all, and i have no clue what im even supposed to do

Answer 4

haha happy to help

Answer 5

awesome

Answer 6

Okay so the initial eqaution is h=-16t^2+vt+s, that is from an object falling from a tall structure to the ground below and to get said equation is how fast the object fell and the amount of time it took to hit the ground

Answer 7

take this example for an example haha h=-16t^2+vt+s, where h is the height (in feet), t is the time in motion (in seconds), v is the initial velocity (in feet per second), and s is the initial height(in feet)
A gymnast dismounts the uneven parallel bars at a height of 8 feet with an initial upward velocity of 8 feet per second. Find the time (in seconds) it takes for the gymnast to reach the ground.
.
from the statement of the problem we have:
v is 8 ft per sec
s is 8 ft
set h to zero (ground) and solve for t:
h=-16t^2+vt+s
0=-16t^2+8t+8
dividing both sides by 8:
0=-2t^2+t+1

Answer 8

multiplying both sides by -1:
0=2t^2-t-1
0=2t^2-2t+t-1
0=(2t^2-2t)+(t-1)
0=2t(t-1)+(t-1)
0=(t-1)(2t+1)
t = {-1/2, 1}
throw out the negative solution leaving:
t = 1 second

Answer 9

I think that should help with the whole thing the rest I can't help you with because it says it's an experiment hope it helps I will be here if you have anymore questions:)
