13. Rotational Inertia & Energy
Intro to Rotational Kinetic Energy
Problem 9c
Textbook Question
Textbook QuestionIf we multiply all the design dimensions of an object by a scaling factor f, its volume and mass will be multiplied by f^3. (b) If a 1/48 scale model has a rotational kinetic energy of 2.5 J, what will be the kinetic energy for the full-scale object of the same material rotating at the same angular velocity?
