A 4.00 kg box sits halfway up a 16.0 m long ramp that is inclined at an angle of 19.0o. You shove a second box, of mass 2.50 kg, that's at the bottom of the ramp so that it starts sliding up the ramp with a speed of 17.0 m/s. It hits the first box, sticks to it, and they both continue to slide up the ramp. The coefficient of kinetic friction between the boxes and the ramp is 0.150. Where, from the bottom of the ramp, do they come to rest?
