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 "v0
", "0" in for "h0
", "48" in for "s(t)" (or "h(t)", etc), and (because you're using "feet") "16" in for "g".
