(b) The rotational kinetic energy is 2 rot rot 2 2 12 ( 2 0 J ) = 2.4 rad/s 27 k g m K KI I ωω = ¡ == The linear speed of the end B is given by (2.4 rad/s)(3.00 m) 7.2 m/s BA B vr ω = , where r AB is the distance between A and B . (c) The maximum angle θ is attained when all the rotational kinetic energy is transformed into potential energy. Moving from the vertical position ( θ = 0) to the maximum angle , the center of mass is elevated by (1 cos ) AC yd Δ= , where d AC = 1.00 m is the distance
