Assuming that Albertine's mass is 60.0kg , what is μk, the coefficient of kinetic friction between the chair and the waxed floor? Use g = 9.80m/s2 for the magnitude of the acceleration due to gravity. Assume that the value of k found in Part A has three significant figures.
Note that if you did not assume that k has three significant figures, it would be impossible to get three significant figures for μk, since the length scale along the bottom of the applet does not allow you to measure distances to that accuracy with different values of k.

How on earth would I know what this problem is asking for? Is the floor tilted? Is someone pushing? Is there a spring involved somewhere with constant k Newtons/meter ?
