The mass density of air on Mars is ρ=0.016 kg/m3. The gravity on Mars is gMars= 3.7 m/s2. The mass density of air on earth under standard pressure and temperature conditions is ρ=1.225 kg/m3. A NASA mars probe weighs 1000 N on Earth. At terminal velocity, the weight of a falling object is equal to the drag force. Assume that the drag coefficient of the parachute used is constant, and has the same value on both Earth or Mars, and...

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...
