## jkev1 Group Title 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). one year ago one year ago

1. jkev1 Group Title

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

h is height??

3. amistre64 Group Title

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

or simply; when t^2 = 100 :/
