(a) Calculate the acceleration of a skier heading down a 10.0° slope, assuming the coefficient of friction for waxed wood on wet snow.

(b) Find the angle of the slope down which this skier could coast at a constant velocity. You can neglect air resistance in both parts, and you will find the result of Exercise 5.9 to be useful. Explicitly show how you follow the steps in the Problem-Solving Strategies.

Data given in Exercise 5.9

Show that the acceleration of any object down an incline where friction behaves simply (that is, where

Note that the acceleration is independent of mass and reduces to the expression found in the previous problem when friction becomes negligibly small ( μ_k=0 ).
