Assuming the earth to be of uniform density, drill a hole through the earth between any two points on the surface of the earth. Install a frictionless tube, and evacuate all the air. Show that the motion of a subway car placed in this tube is simple harmonic motion and evaluate the period of this motion. Note: You must show that your solution is true for a hole between ANY two points on the earth's surface, not just a hold going through the center of the earth. (Hint: Develop a gravitational equivalent of Gauss's Law.)

Say you drill a hole all the way through the Earth, and drop a rock in the hole. It will fall in, then continue "up" the hole once it gets past the center of the Earth, then come to a stop at the other end of the hole, and fall back in, eventually coming back to you (assuming no friction, of course). (a) You can use Gauss' Law to find the force of gravity as a function of distance from...

QUESTION: You are given a meterstick and asked to drill a small hole through it so that, when the stick is pivoted about a horizontal axis through the hole, the period of the pendulum will be a minimum. Where should you drill the hole?(give the distance from the end of the meterstick) Hint: The rotational inertia I of the pendulum can be calculated using the parallel axis theorem.

Q2) To reduce travel time between two cities such as San Francisco and Los Angeles, engineers have proposed building a rail tunnel along a straight line connecting the cities. A train, its d unpropelled by any engine and starting from rest, would fall through the first half of the tunnel and then 10 move up the second half. The technical challenges are immense (the tunnel would need to evacuated) but it is an interesting system to consider. Assuming Earth to...
