The 200g model rocket,Angular acceleration

  1. May 19, 2012 #1
    1. The problem statement, all variables and given/known data
    The 200g model rocket shown in figure 13.24 generates 4.0Nthrust. It spins in a horizontal circle at the end of a 100g rigid rod. what is its angular acceleration?

    2. Relevant equations





    3. The attempt at a solution
    Tnet= F*d= 4.0sin45*0.6
    =1.70N.m
    angular acc=Tnet/MR^2 =1.70/0.2*(0.6)^2
    =23.57 rad/s

    The total moment of inertia is I of rocket plus I of rod.
