A Weight Is Attached to a Spring Suspended Vertically from a Ceiling.When

question 77

Multiple Choice

A weight is attached to a spring suspended vertically from a ceiling.When a driving force is applied to the system, the weight moves vertically from its equilibrium position, and this motion is modeled by
$y = \frac { 1 } { 8 } \sin 2 t + \frac { 1 } { 6 } \cos 2 t$ where y is the distance from equilibrium (in feet) and t is the time (in seconds) .
Find the amplitude of the oscillations of the weight.
