The displacement from equilibrium of an oscillating weight suspended by a spring and subject to the damping effect of friction is given by $y = 2 e ^ { - t } \cos 6 t$ where y is the displacement in centimeters and t is the time in seconds (see figure).Find the displacement when $t = \frac { 1 } { 6 }$ .(Round your answer two decimal places. )

A)0.71 cm
B)1.11 cm
C)1.31 cm
D)-0.91 cm
E)0.91 cm
