1. ### Quantum Mechanics - Supplemental text?

Quantum Mechanics -- Supplemental text? Hello, I'm currently in a quantum mechanics class (undergraduate) that is using Griffiths Intro to Quantum Mechanics (second edition). I've taken solid state physics, electromagnetism, thermodynamics and statistical mechanics, among other physics...

hi all. i'm a junior physics major and i recently have felt like i've hit the total burnout stage of being a physics major. for my electromagnetism class i spend between 20 and 30 hours per week outside of class on the homework (usually 5 or more problems from griffiths) plus reading (with...
3. ### Packing fraction of body-centered cubic lattice - solid state physics

packing fraction of body-centered cubic lattice -- solid state physics Homework Statement This is part of a series of short questions (i.e. prove everything in Kittel Ch. 1, Table 2): Prove that the packing fraction of a BCC (body-centered) cubic lattice is: 1/8 * pi * \sqrt{3}...
4. ### Coriolis Effect with Friction

The following problem is take from Thorton and Marion's Classical Dynamics, 5th edition, p. 408, chapter 10, problem 3. Given A puck of mass m on a merry-go-round (a flat rotating disk) has constant angular velocity \omega and coefficient of static friction between the puck and the disk of...
5. ### Force on Particle in Dust Cloud

[SOLVED] Force on Particle in Dust Cloud The following problem is from Thorton & Marion's Classical Dynamics, Ch. 5 Problem 5-13 (p. 205 in the 5th edition of the text) Homework Statement A planet of density \rho_{1} (spherical core, radius R_{1}) with a thick spherical cloud of dust (density...
6. ### Projectile Fired Up A Hill

the following problem is from the 5th edition of Thorton and Marion's "Classical Dynamics" ch.2 problem 14 p.92 Homework Statement A projectile is fired with initial speed v_0 at an elevation angle of alpha up a hill of slope beta (alpha > beta). (a) how far up the hill will the...
7. ### Classical Mechanics Dynamic Drag Resistance

i'm not even sure where to get started with this one because the thorton and marion classical dynamics book is really awful. BEGIN PROBLEM Suppose a baseball, which has a mass of 150 g and a diameter D of 7 cm is released from rest. For a sphere in air, the dynamic drag is F_d=.25 D^2 V^2...
