We assume you know the following. If you're rusty on any of the following, review chapter 1 in the textbook! We assume you ...

• know how to use the metric system (e.g., what kg and mm are all about).
  
  
• can work with the MKS (meter-kilogram-second) system of units
  
  
• are comfortable doing unit conversions (e.g., miles per hour to m/s)
  
  
• know the basic geometry associated with right-angled triangles, such as:

  sin(q)

  =

  opposite hypotenuse

  
  
• can do basic algebra, and know how to use the quadratic equation.

  If you have an equation that looks like ax² + bx + c = 0, the quadratic equation can be used to solve for x. Generally there are two solutions:

  
  
  

A few questions:

If 100 cm = 1 m, how many cm² = 1 m²?

If you filled 1 cubic meter with water, what mass of water would you have?

Solve for v in the equation:
4v² - 7 = 3 - v²
