[SOLVED] Dynamics Question 1. The problem statement, all variables and given/known data A skier on a slope inclined at 4.7(degrees) to the horizontal pushes on ski poles and starts down the slope. The initial speed is 2.7m/s. The coefficient of kinetic friction between skis and snow is 0.11. Determine how far the skier will slide before coming to rest. 2. Relevant equations Fnet=ma Fg=mg v2=v1+2ad Ff(force of friction)=uk(coefficiant of kinetic friction)xFn(normal force) 3. The attempt at a solution Well after drawing a free body diagram, I concluded that Fnet=fg+fappcos4.7-(force of friction) after subbing in: ma=mg+fappcos4.7-uk(Fn) mass cancels out so: a=g+fappcos4.7-uk(Fn) but now I have no fapp value. I also tried solving it without a Fapp and subbing my acceleration answer into the relevant equation to get the distance, but my answer was wayyyyy of the right answer, which is 13m I wish I could explain more or show that I tired more, but these type of questions always confuse me, I've yet to solve one.
