Two packages at UPS start sliding down the 20∘ ramp. Package A has a mass of 3.00 kg and a coefficient of kinetic friction of 0.220. Package B has a mass of 8.50 kg and a coefficient of kinetic friction of 0.170. Package A and B are touching and package A is closest to the bottom of the ramp. Package B pushes package A down the ramp. The distance from package A to the bottom of the ramp is 2 m. How long does it take package A to reach the bottom?

A box of mass m = 2.00 kg is positioned on a ramp at an angle θ. The length of the ramp (minus the width of the base of the box) is d = 3.00 m. The surface of the ramp has a coefficient of static friction μs = 0.500 and a coefficient of kinetic friction μk = 0.350. The angle θ is slowly increased until the box starts to slide down the ramp. Calculate the angle θmax at which...
