A physical pendulum is composed of a uniform sphere whose center of gravity is attached to a thin rod of negligible mass. The sphere has a moment of inertia of about its center. The mass of the sphere is 2.00 kg, and it has a radius of 30.0 cm. The length of the rod is 50.0 cm. The period for small amplitude oscillations of the physical pendulum is

A 20.0 kg box slides down a 12.0 m long incline at an angle of 30.0 degrees with the horizontal. A force of 50.0 N is applied to the box in the upward direction. The applied force F makes an angle of 0.00 to the incline. If the incline is frictionless, then the increase in the kinetic energy of the box is
