A.Velocity Review problems: Answer in your notebook. You must write the equation you are using, the equation with the numerals and units and then do the math by hand. Round your answer to the 10ths place. Circle your final answer.

1.A bicyclist travels 60.0 kilometers, south, in 3.5 hours; what is her average velocity? v = d/t

2.An airplanes velocity is 420 km/h North and has traveled for 1.25 hours. How far had the plane traveled in this time?
d = v x t

B. Blue Textbook Assignment on velocity:

2. Copy (exactly) the graph – Figure 5 – on page 316 onto graph paper. Glue into your notebook.

4. Page 321 provides scenarios for increasing speed, decreasing speed and changing directions (all forms of acceleration). Sketch a picture (in pencil/colored pencil) that represents each form of acceleration – you can use the ideas in the paragraphs or make up your own. Make sure each sketch is labeled as to which form of acceleration it represents.

D. Review the electromagnetic spectrum
