A block of mass m = 3.0 kg is attached to a cord, which in turn is wrapped around a pulley of mass M = 2 kg and radius R = 5 cm that has the form of a hollow cylinder. Find the speed of the block when the block falls 2 m. (Note: The moment of inertia for a disc is I = 2/5MR2)

If a planet of 3.0 × 1023 kg orbits a star with a period of 65 days at a distance of 1.5 × 107 km, what is the mass of the star?

If a centrifuge has a radius of 4.0 m, what angular velocity (in rad/s) results in a centripetal acceleration of 9g? (g = 9.8 m/s2)

How is eschatology a study of last things and, at the same time, a study of the past and present?
