Two packages at UPS start sliding down a ramp at a 20 degree angle,beginning 2 m from the bottom. Package A is closest to the bottomand has a mass of 6.00 kg and a coefficient of kinetic friction of0.200. Package B is next to Package A and has a mass of 12.0 kg anda coefficient of kinetic friction of 0.170.
How long does it take package A to reach the bottom?
