If the pole-vaulter were to land on concrete rather than on a cushion, the impulse that stops the fall would be:
a. greater because of the rigidity of the concrete. b. greater because the force of impact is greater. c. less, because there is less change in momentum during the stop. d. less, because he would come to a stop over a shorter period of time. e. the same because impulse is the change in momentum of the object.

A triatomic molecule is modeled as follows: mass m is at the origin, mass 2m is at x = a, and mass 3m is at x = 2a
(a) What is the amount of inertia about the origin? (b) What is the moment of inertia about the center of mass?
A mass m is attached to a vertical spring with a force constant k, it oscillates with a period T. If the spring is cut to one third of its original length and the same mass is attached to it, the new period of oscillation will be
A) less than T. B) greater than T. C) equal to T. D) It could be greater or less than T, depending on how you cut the spring.
