An Object Attached to a Coiled Spring Is Pulled Down $a = 5 ; \quad \mathrm { T } = 3$

question 62

Multiple Choice

An object attached to a coiled spring is pulled down a distance a from its rest position and then released. Assuming that
the motion is simple harmonic with period T, write an equation that relates the displacement d of the object from its rest
position after t seconds. Also assume that the positive direction of the motion is up.
- $a = 5 ; \quad \mathrm { T } = 3$ seconds

• A) \(\mathrm { d } = - 5 \cos \left( \frac { 1 } { 3 } \pi \mathrm { t } \right)\)
• B) \(\mathrm { d } = - 3 \cos \left( \frac { 2 } { 5 } \pi \mathrm { t } \right)\)
• C) \(d = - 5 \sin \left( \frac { 2 } { 3 } \pi t \right)\)
• D) \(\mathrm { d } = - 5 \cos \left( \frac { 2 } { 3 } \pi \mathrm { t } \right)\)
