Question

Find the time, t, in seconds it takes for an object to fall from the top of a 1600 ft building by using the function (hint: set h=0).

Answer 1

the function is h=-16t^2+1600

Answer 2

h is height??

Answer 3

\[mgh=\frac12mv^2\]
\[v=\sqrt{2gh}\]
\[\sqrt{2gh}=gt\]
\[\frac{\sqrt{2gh}}{g}=t\]
maybe

Answer 4

or simply; when t^2 = 100 :/
