A toy rocket was launched from the ground straight up with an initial velocity of 64 ft/sec. How many seconds after launch was the rocket 48 feet above the ground?

What formula did they give you? It should have looked something like the formula explained

**here**.

If not, please reply with corrections. If so, then please reply showing how far you've gotten and where you're stuck, starting with plugging "64" in for "v

_{0}", "0" in for "h

_{0}", "48" in for "s(t)" (or "h(t)", etc), and (because you're using "feet") "16" in for "g".

Thank you!
