While I bitched about my classes last term, that was just me getting into general frustration.
Now I've hit a class that is *legitimately* balls to the wall in difficulty, AND I have no way of making sure that I know the material.
Dynamics. Your particle is moving at a tangential acceleration of (30 - 0.001t)ft/s^2 from rest around a circular path of a 300-foot radius. Find the displacement of the particle when its velocity is equal to 20 ft/s, and find the time required for the particle to reach this speed.
I want to know how to do this, and I want to be good at it, but how the fuck do I even know if I'm doing it right?
