Question

I NEED CALCULUS HELP!! PLEASE!

Answer 1

A stone was dropped off a cliff and hit the ground with a speed of 104 ft/s. What is the height of the cliff?

Answer 2

Thnks!!!!

Answer 3

i guess you are supposed to use
\[h(t)=-16t^2+h_0\] for your equation of height. you know that the initial velocity was 0 because it was dropped. you also know that it hits the ground when
\[t=\frac{\sqrt{h_0}}{16}\] and that
\[-32t=-104\] for that value of t

Answer 4

typo there it should be it hits the ground when
\[t=\frac{\sqrt{h_0}}{4}\]

Answer 5

ok

Answer 6

so it hits the ground when
\[t=3.25\] and use that to solve for
\[h_0\]

Answer 7

ok thanks I got it!!!
