QUESTION:
Problem 7CQ
Give a common, everyday example for each of the following: (a) An object that has zero rotational kinetic energy but nonzero translational kinetic energy. (b) An object that has zero translational kinetic energy but nonzero rotational kinetic energy. (c) An object that has nonzero rotational and translational kinetic energies.
ANSWER:
Step 1 of 3
Part a
For an object to have zero rotational kinetic energy, it must not be rotating about an axis. Suppose, a book is pushed on a table. It is not rotating, but it gains a speed. So, its rotational kinetic energy is zero and translational kinetic energy is nonzero.
