1. Study for your quiz (anything dealing with kinematics is fair game). You may want to review this website if you still don't understand calculus-based kinematics: http://physics.info/kinematics-calculus/ and http://physics.info/kinematics-calculus/practice.shtml

*in general, http://physics.info is another text-source we'll be relying on so... get used to seeing this come up more often! You may just want to review what they have to say about kinematics (Chapter 1.1)

**Practice Problem: 
An object moves along the x-axis according to the function x(t) = 5 – 2t + 3t^2 – 0.5t^3, where t is time measured in seconds and x is position measured in meters. (a) Determine expressions for this object’s velocity and acceleration as functions of time. (b) For the interval of time t = 0 to t = 4.0 s determine: (b) average acceleration, (c) maximum rate of acceleration, (d) average velocity, (e) maximum speed, and (f) maximum distance from the origin.

Helpful pages for derivatives: http://www.mathsisfun.com/calculus/derivatives-introduction.html and http://www.mathsisfun.com/calculus/derivatives-rules.html

2. Read (only, no annotations needed) Chapter 1.2 Dynamics from that same website (above).

3. Read and annotate Chapter 4 from Openstax textbook.

4. Complete Openstax p.162 #31, p.163 #32, 33, 41, 42
