1) If an arrow is shot straight upward with a velocity of 96 feet per second (ft/sec) from an altitude of 6 feet, for how many seconds is this arrow more than 86 feet high?

Note
If an object is given an initial velocity straight upward of "v lower case 0" feet per second from a height of "s lower case 0" feet, then its altitude "S" after "t" seconds is given by the formula:

S = -16t squared + v lower case 0 t + s lower case 0

Solution Summary

The solution determines the time for which an arrow shot straight upward is above a particular height.

Solution Preview

S = -16t ^2 + Vo t + So

So= 6 feet
Vo= 96 ft/sec

we have to check when S>86
or S = -16t^2+96 t +6 >86
or -16t^2+96 t -80 ...
