An object consists of four small spheres attached to the ends of two thin rods that are connected perpendicularly at their centers, forming a cross. Assume each sphere has a mass of m and a radius that is negligible compared to the distance R that each is from the cross’s center (in other words, we can model each as if it were a particle), and that each rod has a mass of m/2. What is a for this object for rotations around an axis perpendicular to the plane of the cross is _____ for rotations around an axis that goes along one of the rods is _____ (Hint: The object’s total mass is not m.)

An artificial pond was constructed in the local park last year by digging a hole in the shape of a perfect hemisphere of radius 2 m, and then filling it with water. Now, a year later, the pond needs cleaning, and the city workers need to pump out all of the water. In order to do so, energy must be expended to lift the water (working against gravity) from down inside the pond up to ground level. It is known that the energy, E required to lift a mass m (in kg) to a height h (in m) is given by E = mgh (where g can be taken to be 10 m/s2). You can take the density of water to be 1000 kg/m3. How much energy is required in total to pump all of the water out the pond?
Two identical spheres of radius 8 in. and weighing 2 lb on the surface of the earth are placed in contact. Find the gravitational attraction between them.
A circular solid disc of uniform thickness 20 mm, radius 200 mm and 20 kg, is used as a flywheel If it rotates at 600 rpm, what is the kinetic energy of the flywheel.
Zorch, an archenemy of Superman, decides to slow Earth’s rotation to once per 29 h by exerting a force parallel to the equator, opposing the rotation. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.15 × 107 N. For the purposes calculations in this problem you should treat the Earth as a sphere of uniform density even though it isn't. a. How long, in seconds, must Zorch push with this force to accomplish his goal? (This period gives Superman time to devote to other villains.)
