A spring (with a mass negligible in comparison to the mass of a child) in a child's toy will compress 3.20 cm when a 75.0 kg person is supported, leading to a spring constant of 2.3×104N/m2.3×104N/m. When compressed 5.00 cm additionally and allowed to oscillate, this system has a frequency of 2.79 Hz. Which of the following would need to increase in order to decrease the period by a factor of 10?

• If the moment of inertia about the mediolateral (transverse) axis through an object’s COM is known, can the moment of inertia of the object be computed about another axis of rotation? If so, how? With the information given in this example, could the moment of inertia be computed about any axis of rotation (e.g. the object’s anteroposterior axis or longitudinal axis)? Why or why not?
