3 part question about angular/tangential acceleration

  1. Feb 21, 2016 #1
    1. The problem statement, all variables and given/known data

    Hi all,
    Assignment due at midnight ET, these are the last questions i'm missing
    1. A merry-go-round makes one complete revolution in 15.7 s. A 53.1 kg child sits on the horizontal floor of the merry-go-round 4.3 m from the center. Find the child’s acceleration. The acceleration of gravity is 9.8 m/s^2 . Answer in units of m/s^2 .
    2. Find the horizontal force of friction that acts on the child. Answer in units of N.
    3. What minimum coefficient of static friction is necessary to keep the child from slipping?

    2. Relevant equations

    3. The attempt at a solution
    Teacher did not attempt to teach us any relevant formulas for this unit. It's pretty sad.
