Kendra is wrapping a cake that is in a box with a shape of a cube. She wants to know the length of a side so that she makes sure that she has enough wrapping paper. The box says that it contains 343 cubic inches of cake. What is the length of one of the sides of Kendra's cake?

The volume of a cube with side lenght s is given by: V=s3
Given that V=343 cubic inches, then: $$\displaystyle{343}={s}^{{3}}$$ 3sqrt343=s
Since $$\displaystyle{7}^{{3}}={343}$$, then: s=7
So, the side lenght of Kendra's cake is 7 inches.

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 $$\displaystyle\mu_{{k}}$$, the coefficient of kinetic friction between the chair and the waxed floor? Use $$\displaystyle{g}={9.80}\frac{{m}}{{s}^{{2}}}$$ 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 $$\displaystyle\mu_{{k}}$$, 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.
