Two weights (weight 1 and weight 2 ) are suspended from the ceiling by springs. At time $\mathrm{t}=0$ ( $\mathrm{t}$ in seconds), the weights are set in motion and begin bobbing up and down. Eventually, however, the oscillation of both weights dies down. The following equations describe the distance of each weight from the ceiling as a function of time:
$d_{1}=4+3 \cos (\pi t) e^{-0.3 t} \text { and } d_{2}=2+2 \cos (2 \pi t) e^{-0.5 t} \text {. }$
Which weight is closer to the ceiling at time $t=20$ ?
A) Weight 1
B) Weight 2
