Homework Statement
The ratio of nitrogen to oxygen at sea level is 4.0:1. Use Laplace's law of
isothermal atmospheres to calculate the same ratio for 3255m above sea level
Assume that T = 273 K

P_fN2 = P_iN2 * e^-\Big({\frac{M_N2 g}{R T}}*h\Big)
P_fO2 = P_iO2 *...
Okay, I understand that part of it, but what direction would it need to be thrown at? I would think that either east or west would be correct since things don't tend to orbit the poles. Throwing it to the east would be going against Earth's rotation, and thus would ensure that it returns. While...
I assume it would leave the atmosphere at some point, since Earth is a sphere, but wouldn't that be the case at any angle between 0 and 180? Would it continue on after it left the atmosphere or would it go into an orbit?

If you were on the top of Mt. Chimborazo in Ecuador (0°S, 80°W, elevation 20,564 ft), with what minimum speed (and in what direction) would you have to throw a baseball horizontally so that it would go into a circular orbit
about the earth? (Neglect air friction. Assume a...
I calculated ϴ1 to be approx -11.3° and ϴ2 to be approx 38.7°. Do these seem reasonable?
I see where those equations are incorrect. I didn't account for forces acting in more than on direction. Is the last equation
T2Cosϴ2 - 444.8 - T1Cosϴ1 = 0 ?
Homework Statement
A rope is connected between two fixed points that are separated horizontally from one another by 10 m. The point on the left at a height of 5 m [coordinates (0,5m)], and point on the right is at a height of 10 m [coordinates
(10m,10m)]. A 100 lbs weight hangs from the rope...
