As depicted in the applet, Albertine finds herself in a very odd contraption. She sits in a reclining chair, in front of a large, compressed spring. The spring is compressed 5.00 m from its equilibrium position, and a glass sits 19.8m from her outstretched foot.
a)Assuming that Albertine's mass is 60.0kg , what is , the coefficient of kinetic friction between the chair and the waxed floor? Use 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 , 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.
