Solve the Problem Let V Represent the Wind Speed (Velocity) in Feet Per

question 255

Multiple Choice

Solve the problem.
-An experiment in a wind tunnel generates cyclic waves. The following data is collected for 52 seconds: $$\begin{array} { c | c } \text { Time } & \text { Wind speed } \\\text { (in seconds) } & \text { (in feet per second) } \\\hline 0 & 16 \\\hline 13 & 38 \\\hline 26 & 60 \\\hline 39 & 38 \\\hline 52 & 16\end{array}$$ Let V represent the wind speed (velocity) in feet per second and let t represent the time in seconds. Write a sine equation that describes the wave.

• A) \(V = 22 \sin \left( \frac { \pi } { 26 } t - \frac { \pi } { 2 } \right) + 38\)
• B) \(V = 44 \sin ( 52 t - 26 ) + 22\)
• C) \(V = 60 \sin \left( \frac { \pi } { 26 } t - \frac { \pi } { 2 } \right) + 16\)
• D) \(V = 60 \sin ( 52 t - 26 ) + 16\)
