I'm doing my math homework!
Problem: How does the distance change as the person moves?
Assumptions: The farther away from the clear zone, the larger the clear zone will be.
Method: Step 1: Setup: (1) Work in a space near a large smooth wall. A classroom chalkboard is ideal. The CBR must always be between 0.5m and 6.0m from the wall. Make sure there are no objects in the clear zone between the CBR and the wall.
(2)Connect the CBR to the calculator with the connecting cable. Make sure the connections are secure. (3) Turn on the calculator and press (pgrm) (4) Choose RANGER. (5) Press (enter) (enter) to display the main menu. (6) Make sure the cursor is beside start now. If it is not, use the arrow keys to move it. (7) Hold the calculator in one hand and the CBR in the other. Aim the sensor directly at the wall. Step 2: Collect and graph the data: (1) When you are ready to start press (enter). Follow the instructions on the screen. As you move toward the wall or away from the wall, the calculator displays a distance time graph recording your distance to the wall. To make the calculator redraw the graph in a better position on the screen press (enter) than (1). (2) To repeat press (enter) than (3).
*Try moving toward the wall at a steady rate.
*Try moving away from the wall at a steady rate.
*Try moving more quickly or more slowly.
*Try different patterns of moving, including standing still.
Repeat until you are satisfied with the result. (3) Leave the graph on the screen while you complete the following exercises. Since the data for this graph are in your calculator, you can disconnect the cable so that someone else can use the CBR.
Observations: Graph for question #3(a) done on separate piece of graph paper attached.
Calculations: There were no calculations conducted in this investigation.
Discussion and conclusions:
1. (a) The physical quantity that is represented on the horizontal axis is time.
(b) The physical quantity that is represented on the vertical axis is distance.
2. (a) As you move towards the wall the distance increases. As you move away from the wall the distance decreases.
(b) As you move quickly the increase or decrease becomes steeper.
(c) As you stand still the line does not move.
3. (a) Graph done on separate piece of graph paper attached.
(b) Our screen represents that we neither moved away or toward the wall.
4. (a) The person was 2.499 m away from the wall when the calculator plotted the point under the flashing cursor.
(b) 0.65 seconds after the plotting started occurring.
(c) The person was moving away from the wall because the x axis representing time increased as time went by.
(d) The person moved away from the wall at a steady pace.
Please don't copy my homework it's wrong
