Question

Find the exact time it takes a stone to reach the ground if it is dropped from a bridge that is 200 ft. high. --- "The time t it takes an object dropped from a height h to reach the ground is given by the equation t=(square rooted)h/16

Answer 1

put h = 200ft in your equation and get t.

Answer 2

I did that but i think i got the wrong answer, so what did you get?

Answer 3

I got the answer 3.53 but got it wrong, so...

Answer 4

??

Answer 5

can you put up your equation more clearly? is it t = sqrt(h/16)
or t = sqrt(h)/16

Answer 6

t=sqrt(h/16)

Answer 7

and h is in feet?

Answer 8

yes

Answer 9

then it has to be t = sqrt(200/16) = 3.5 seconds

Answer 10

wow, so i just added the extra 3 at the end and got it marked wrongg...

Answer 11

or actually 3.5 unit time measure.

Answer 12

yeah i said 3.53 seconds

Answer 13

the correct answer is 3.53553391 unit time measure.

Answer 14

sigh. no one actually would say that though , some "real life problem'. i dislike my teacher.

Answer 15

you shouldn't have said seconds. you probably got marked wrong since you answered in seconds. ask your teacher why they marked it wrong. Because your answer is correct.

Answer 16

alright.

Answer 17

unless the problem specified that t was in seconds, you shouldn't have answered in seconds.
