Determine the Equation of the Graph $= 2 \pi \sqrt { 0.21875 }$

question 216

Multiple Choice

Determine the equation of the graph.
-Determine the period and frequency of oscillation when a pendulum of length 7 feet is released after being displaced 2 radians. Round constants to 8 decimal places, if necessary.

• A) Period \(= 2 \pi \sqrt { 0.21875 }\) sec, frequency \(= \frac { 1 } { 2 \pi } \sqrt { 4.57142857 }\) cycles per sec
• B) Period \(= 2 \pi \sqrt { 4.57142857 }\) sec, frequency \(= \frac { 1 } { 2 \pi } \sqrt { 0.21875 }\) cycles per sec
• C) Period \(= 7 \pi \mathrm { sec }\), frequency \(= \frac { 1 } { 7 \pi }\) cycles per sec
• D) Period \(= \frac { \pi } { 7 }\) sec, frequency \(= \frac { 7 } { \pi }\) cycles per sec
