Question
Five objects of equal mass are shown below together with the axis about which they are rotating. Select from the pull-down menus the objects in order of increasing rotational energy, with 1 having the smallest rotational energy and 5 having the highest rotational energy.
THANKS FOR HELP!
Five objects of equal mass are shown below together with the axis about which they are rotating. Select from the pull-down menus the objects in order of increasing rotational energy, with 1 having the smallest rotational energy and 5 having the highest rotational energy. Thin cylindrical shell, about cylinder axis with R = 2 m and omega gw = 5 red/s Solid Cylinder, about cylinder axis with R = 3 m and omega gw = 5 rad/s Thin rod, about axis through center, perpendicular to the length with I = 9 m and omega gw = 5 rad/s Solid Sphere, about any diameter, with R = 3 m and omega gw = 6 rad/s. Thin Spherical shag about any diameter, with R = 3 m and omega gw = 5 rad/sExplanation / Answer
K.E=0.5*I*w^2 a)Ihcyl=mr^2 K.e=50m b)Iscyl=mr^2/2 K.e=56.25m c)Irod=ml^2/12 K.e=(rod's specs missing) d)Isolsphere=(2/5)*mr^2 K.e=64.8m e)Ihollosphere=(2/3)*mr^2 K.e=75m hope u can rearrange them as u need :)
