Question

the formula v=√64h can be used to find the velocity v in feet per second of an object that has fallen h feet. Find the velocity of an object that has fallen 30 feet. Round your answer to the nearest hundredth

Answer 1

`v=\sqrt[]{64h}`

start by replacing h for 30ft which is the height that the object has fallen

`\begin{gathered} v=\sqrt[]{64\cdot30} \\ v=\sqrt[]{1920} \\ v=43.8178\approx43.82 \end{gathered}`

the velocity is approximately 43.82 feet per second
