Assuming that Albertine's mass is 60.0 , what is , the coefficient of kinetic friction between the chair and the waxed floor? Use = 9.80 for the magnitude of the acceleration due to gravity. Assume that the value of found in Part A has three significant figures.

Note that if you did not assume that has three significant figures, it would be impossible to get three significant figures for , since the length scale along the bottom of the applet does not allow you to measure distances to that accuracy with different values of .

  1. .5(k)x^2=m(9.81)(d)(mk)

    mk=coefficient of friction
    d= is distance traveled
    m=is mass of albertine in kg
    x=distance spring was displaced
    k=spring constant
    so enter in everything you do know and solve for mk.

    answer: mk=.102
