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 $t = \frac { 1 } { 5 }$ .Round your answer to two decimal places.
A)0.89 cm
B)0.59 cm
C)0.99 cm
D)1.09 cm
E)0.79 cm
