Question

An object will take t sec to drop d feet, where t = \[\sqrt{d/16}\]. what distance will it drop in \[\sqrt{19}/2\] sec?
I got 19ft.

Answer 1

i think it might be 38 though

Answer 2

76?

Answer 3

\[t= \sqrt{d/16}={\sqrt{d}\over4}\]

Answer 4

sqrt(19)/2=sqrt(d/16)
19/4=d/16
d=76?

Answer 5

\[{\sqrt{19}\over2}={\sqrt{d}\over4}\]\[\sqrt d = 2 \sqrt{19}\]
\[\huge \therefore d=76\]

Answer 6

But the question isn't asking the value of d

Answer 7

yes it is ... 76 ft

Answer 8

d = distance
distance = unknown
unknown = answer
therefore, d = answer

Answer 9

Yes, answer is 76 feet

Answer 10

either way i got it wrong thanks for all your help. i got 2 more i want to check but im too tired to type. gonna play a video game, hehe.
