A model rocket is launched with an initial upward velocity of 140 ft/s . The rocket's height h (in feet) after t seconds is given by the following.

Find all values of t for which the rocket's height is 68 feet.

Step-by-step explanation:

If you're looking for the times, t, when the height, h, is 68, then sub in 68 for h and factor the resulting quadratic.

and, getting everything on one side and setting the quadratic equal to 0:

Plug this into the quadratic formula and solve for t.

t = .516 sec and

t = 8.234 sec
