An Object Weighing W Pounds Is Suspended from the Ceiling y=12et4cos2t,t>0y = \frac { 1 } { 2 } e ^ { - \frac { t } { 4 } } \cos 2 t , t > 0

question 195

Multiple Choice

An object weighing W pounds is suspended from the ceiling by a steel spring (see figure) .The weight is pulled downward (positive direction) from its equilibrium position and released.The resulting motion of the weight is described by the function
y=12et4cos2t,t>0y = \frac { 1 } { 2 } e ^ { - \frac { t } { 4 } } \cos 2 t , t > 0
Where y is the distance (in feet) and t is the time (in seconds) .
Use a graphing utility to select the graph of the function.
