1. In the figure the mass of the box is 0.15 kg. It slides down the track from point A and reaches point B with a speed of 5.10 m/s. From point B, it slides on a level surface a distance of 4.00 m to point C, where it comes to rest. (a) What is the coefficient of kinetic friction on the horizontal surface? (b) How much work is done on the package by friction as it slides down the circular arc from A to B? A- R=1.80 m m = 0.150 kg 4.0 m В
