Today we started studying motion in class with some notes (see link)
I discussed problems with #5 (it was tough) on the homework; basically the person on the bus is walking one way but moving another relative to the ground. Walking backward, moving forward in the bus's direction (as long as the bus is moving faster)... we discussed with a diagram.
Most classes (except 3rd per.) finished finding slope on yesterday's graphing WS and some people remembered units!!!! Hooray - a slope that means something! :) In our case it was meters of tree growth per year on average.
I promised an optional assignment would be posted here. It is:
You are an engineer building a new shopping center. The local city government requires all new buildings to have temporary holding ponds for water runoff during rain to prevent flooding to existing homes and buildings downstream. You must determine the volume of water that must be stored in this pond during a spring downpour; 6.00 centimeters (2.36 inches). You may choose to use metric or standard units for your calculations. Show your work (NEATLY), circle your answer and units, and write an explanation of which system of measurement is easier to use for this real-world engineering task.
Your building and parking lot measurements are:
Building: 32.9 meters long x 58.4 meters wide OR 107 and 30/32 feet x 191 and 5/8 feet
Parking lot: 60.2 meters long x 40.3 meters wide OR 197 and 1/2 feet x 132 and 3/16 feet.
Due Tuesday.
