If you had a large number of 50 gram masses of total mass m distributed equidistantly from the axis of rotation, what single formula could be used to find the moment of inertia of this shape? what would you call this shape? give a real-life example of an object that has this approximate shape.

Astudent on a piano stool rotates at a rate of 2.85 rev/s. the student holds a 1.25kg mass in each outstretched arm, 0.76m from the axis of rotation. the combined momment of inertia of the student and the stool without the two masses, is 5.45kg*m^2, a value that remains constant. as the student pulls his arms inward, his rate of rotation increases to 3.50 rev/s. how far are the masses from the axis of rotation at this time?

The rotational kinetic energy term is often called the kinetic energy in the center of mass, while the translational kinetic energy term is called the kinetic energy of the center of mass. you found that the total kinetic energy is the sum of the kinetic energy in the center of mass plus the kinetic energy of the center of mass. a similar decomposition exists for angular and linear momentum. there are also related decompositions that work for systems of masses, not just rigid bodies like a dumbbell. it is important to understand the applicability of the formula ktot=kr+kt. which of the following conditions are necessary for the formula to be valid? check all that apply. a. the velocity vector v must be perpendicular to the axis of rotation. b.the velocity vector must be perpendicular or parallel to the axis of rotation. c.the moment of inertia must be taken about an axis through the center of mass.
