Phy53 Lecture Summary -- Dr. Brown -- 14 Sep 2010 -- 11:40 - 12:55
hwk probs examples ---> work-energy
only one solution for #10
1. rotating turntable with piece of chocolate [meta comment -- start with N2!; follow rubric]
v = r \omega ==> a_r = v^2/r = r \omega^2
2. prob #8
diffy-q : \frac{dv_t}{dt}= -\frac{\mu_k v^2}{R}
3. prob #4 sort of
w-e in 1D
N2 w/chain rule
defines work and kinetic energy -- redoes 3 [that was easy]
now gen. to 3D
