An Object Is Attached to a Coiled Spring $d = 6 \cos 5 t$

question 307

Multiple Choice

An object is attached to a coiled spring. The object is pulled down (negative direction from the rest position) and
then released. Write an equation for the distance of the object from its rest position after t seconds.
- $d = 6 \cos 5 t$ meters

• A) displacement \(= 6\) meters; period \(= \frac { 2 } { 5 } \pi\) seconds; \(\mathrm { f } = \frac { 5 } { 2 \pi }\) oscillations/second
• B) displacement \(= 6\) meters; period \(= \frac { 5 } { 2 \pi }\) seconds; \(\mathrm { f } = \frac { 2 } { 5 } \pi\) oscillations/second
• C) displacement \(= - 6\) meters; period \(= \frac { 2 } { 5 } \pi\) seconds; \(\mathrm { f } = \frac { 5 } { 2 \pi }\) oscillations/second
• D) displacement \(= 6\) meters; period \(= 5 \pi\) seconds; \(\mathrm { f } = \frac { 5 } { \pi }\) oscillations/second
