Consider a solid ball (sphere) of uniform density. Its radius is 10 cm and mass is 0.1 kg. What is the ball's moment of inertia if it is rotating about its center? Enter in a numerical answer. Assume the SI base units of moment of inertia (but do not enter the units and do not use scientific notation).

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
