A farmer fell asleep under a tree in his apple orchard while thinking about pie. While he was sleeping, a squirrel knocked an apple off a branch of the tree. The function f (d) = (see photo) can be used to find the amount of time in seconds that it takes for the apple to drop acertain distance d, where d is in meters.Step 1 of 3 : If the apple was connected to a branch that was 3 meters above the farmer's head, how long would it take before the applehit the top of the farmer's head? Round your answers to the nearest hundredth.

Solution

Step 1

Write the time function equation


f(d)\text{ = }\sqrt{(2d)/(9.8)}

Step 2

d = 3 meters


\begin{gathered} f(3)\text{ = }\sqrt{(2*3)/(9.8)} \\ f(3)\text{ = 0.78 seconds} \end{gathered}

Final answer

0.78 seconds
