2. A sledder of mass m is sliding down a snowy hill with initial speed v0. The hill steepness is a small positive angle El relative to horizontal. The coefcients of static and kinetic friction between the sledder and snow are p3 and pk. The acceleration due to gravity has magnitude g. Neglect air resistance. a. [3pts} Draw a free-bndy diagram for the sledder. Use coordinates adaptedftilted to the slope, rather than to gravity. Don't forget labels! Remember, tails of vectors must all start at the dot! Think hard about the direction of the force of friction! b. {Spts} What is the magnitude of the acceleration |u| of the sledder? Express your answer in terms of one or more of these: n1, p5, pk, I}, and g. c. {4pts} What is the angle I} that would cause the sledder to be in equilibrium? Express your answer in terms of one or more of these: m, p5, pk, El, and g
