Suppose a small box with a mass of 4.00kg is moving at 10.0m/s along a flat horizontal surface immediately before it begins travelling down a slope. The slope is at an angle of 20.0∘, has a length of 8.00m, and the coefficent of kinetic friction between the slope and the box is 0.750. What is the velocity of the box when it reaches the bottom of the slope?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)
