Give us a hint... How are you thinking of starting it? What have you tried so far? What kind of a problem does it look like to you?
Hmm...I think it might be an energy problem, and I think I should use the 2nd and 3rd diagrams to solve it, but I kind of get lost from there.
Or maybe solve for the force of friction and the kinetic energy?
Actually...I just got it. I looked at another post about 18 and I realized that mew times the force due to gravity times the displacement was equal to the difference in kinetic energy. Thanks anyway for making me think about it more.
