A child goes down a playground slide with an acceleration of 1.24 m/s^2.
Find the coefficient of kinetic friction between the child and the slide if the slide is inclined at an angle of 32.0 degrees below the horizontal.

  1. Why would someone volunteer to help students take on a student that changed their name every one minute? Could it be the student is answer grazing?

    The childs weight has two components, down the slide, normal to the slide.
    down the slide=mg*sinTheta
    normal to slide=mg*cosTheta

    so
    net force = m*a
    mg*sinTheta-mu*mg*cosTheta= ma

    solve for mu.
