Two packages at UPS start sliding down the \( 20.0^{\circ} \) ramp Part A shown in (Flgure 1). Package A has a mass of \( 8.00 \mathrm{~kg} \) and a coofficient of kinetic friction of 0.400. Package. B has a How long does it take package A to reach the botlom? mass of \( 10.0 \mathrm{~kg} \) and a coefficient af kinetic friction of \( 0.150 \). Express your answer with the appropriate units.
