Phys 341: Homework #2 Solutions 1. (a) The semimajor axis of HSTs orbit equals the radius of the Earth (R = 6378 km) plus the altitude above the surface (about 380 miles, or about 600 km). So lets call it a = 7000 km. From the generalized form of Kep
Phys 341: Homework #3 Solutions 1. As a reminder, here is the gure:
(a) The dotted line corresponds to the more massive star (#1) and the dashed line to the less massive star (#2). We know this because the same force acts on both stars, and by F = m
Phys 341: Homework #4 Solutions 1. (a) Recall that the center of mass is dened such that mA aA = mB aB , so we have aB 1 mA = = = 2.15 mB aA 0.466 Since mA /mB > 1, star A is more massive than star B. (b) Recall that the distance can be determined fr
Phys 341: Homework #5 Solutions 1. (a) If the Earth and Moon are tidally locked and the Earths rotation period is 47 days, the the Moons orbital period is also P = 47 days = 4.1 106 s. Then from Keplers Third Law, the semimajor axis of the Moons orb
