Hi I am having trouble with a problem that involves angular velocity. The problem states: The rigid object shown is rotated about an axis perpendicular to the paper and through point P. The total kinetic energy of the object as it rotates is equal to 1.4 J. If M = 1.3 kg and L = 0.50 m, what is the angular velocity of the object? Neglect the mass of the connecting rods and treat the masses as particles. There is an illustration that I tried to insert below...if it does not show, here is a description: The object has a total of 4 spheres. The first 2 spheres are each of mass M and are attached to opposite ends of a rod whose length is 2L. The other 2 spheres are each of mass 2M and are attached to opposite ends of a rod whose length is L. The rods cross one another at their midpoints. The equations I was trying to use are: KE=(1/2)IW^2 (I'm using W for angular velocity) I also know KE=(1/2)mv^2 (for linear values) and v=WR. I don't know where to go from here. Could someone help me?
