1. The problem statement, all variables and given/known data A child goes down a playground slide with an acceleration of 1.26 m/s^2. Find the coefficient of the kinetic friction between the child and the slide if the slide is inclined at an angle of 33 degrees below horizontal. 2. Relevant equations F=MA Kinetic Friction = (Coefficient)N 3. The attempt at a solution I'm assuming I need to find the X and Y components using 33 degrees and gravity? (-9.81Cosine(-33) = -8.66 (-9.81)Sin(-33) = 4.6 Now I'm pretty lost. I'm having a hard time understanding how f=ma and Fk = (μk)N relate to each other. I think I can plug in MA into N? Fk = (uk)(ma) ?
