1. Write your own problem that requires you to add vectors that are parallel to each other and going in the same direction. Solve the problem and include both the algebraic solution and a diagram for your solution.
2. Write your own vector problem that requires you to add vectors that are parallel to each other but going in opposite directions. Solve the problem and include both the algebraic solution and a diagram for your solution.
3. Write your own vector problem that requires you to break at least two vectors into components, add them together and find the resultant vector. Solve the problem and include both the algebraic solution and a diagram for your solution.

Explain why a combination of high, hot, and humid conditions creates high density altitude flying conditions.

Now, synthesize and apply the information you reviewed on the concept of density altitude to address the following:
1. Using terms that an average person could easily understand and by applying related concepts and terms, present a practical definition of density altitude.

2. Fill in the blank: If the value of density altitude is relatively high, the air density is relatively

3. Of the four main forces acting on aircraft, name the ones that are reduced by high density altitude flying conditions.

4. Of the four main forces acting on aircraft, name the one that can be altered, in the process of proper flight planning, to reduce the impact of high density altitude flying conditions.

5. Explain why a combination of high, hot, and humid conditions creates high density altitude flying conditions. Your explanation should involve a discussion of how air temperature, pressure, humidity affect air density and thus the density altitude. 6. Apply your understanding of density altitude to answer the following scenario-based question:
A general aviation pilot in training is scheduled to do repeated touch and go’s in a Cessna 172 at Bob Adams Field in Steamboat Springs, Colorado on a mid-afternoon in early August. Explain why the aircraft’s ability to take off, land, and climb during the touch and go’s will be negatively impacted. Include an image within your document that visualizes the explanation.

Determine the vertical position and velocity of the ball. Enter your values in your data table.

Lab Energy of the Tossed Ball

Procedure:
1. Measure and record the mass of the ball you plan to use in this experiment.
2. Connect the Motion Detector to the DIG/SONIC 1 channel of the interface. Place the Motion Detector on the floor and protect it by placing a wire basket over it.
3. Hold the ball directly above the Motion Detector. Have your partner click to begin data collection. Toss the ball straight upward above the Motion Detector and let it fall back toward the Motion Detector catch the ball before it hits the detector.
Note: Use two hands, be sure to pull your hands away from the ball after it starts moving so they are not picked up by the Motion Detector. Throw the ball so it moves vertically above the detector. Verify that the position vs. time graph corresponding to the free-fall motion is parabolic in shape, without spikes or flat regions, before you continue. This step may require some practice. If necessary, repeat the toss, until you get a good graph. When you have good data on the screen, proceed to the Analysis section.
4. Click on the Examine button, , and move the mouse across the position or velocity graphs of the motion of the ball to answer these questions.
⦁ Identify the portion of each graph where the ball had just left your hands and was in free fall. Determine the vertical position and velocity of the ball. Enter your values in your data table.
⦁ Identify the point on each graph where the ball was at the top of its path. Determine the time, vertical position, and velocity. Enter your values in your data table.
⦁ Find a time where the ball was moving downward, just before it was caught. Measure and record the vertical position and velocity of the ball at that time.
⦁ Collect two more times on the way up and on the way down for a total of seven data points.
⦁ For each of the seven points in your data table, calculate:

Conduct your own physical experiment using the scientific method. Research the scientific method and give a 1 page written description of each step. You will then document your process with photos and/or video.

How does the work done in walking compare to the work done in running? Explain why you would expect it to be this way.

All measurements should be done very carefully. Be sure to include units with all measurements and calculations.

⦁ Find the weight of yourself and the other person. This needs to be in newtons. If your scale weighs in pounds, convert the weight in pounds to newtons. You can easily find the conversion factor by searching the internet . Record the weights in the data table below. You are Walker 1 and Runner 1 – so same weight for both. The other person is Walker 2 and Runner 2.
⦁ Measure the height of the stairs by measuring the height of one step and counting the number of steps. You should measure the height of the step in centimeters. Then divide the measurement by 100 to get meters. Enter the height value and the number of stairs in the data table. Note that you put the same measurement into each of the four cells under “Height of Step”, and the same number of steps into each cell under “Number of Steps”.

⦁ Measure the time for each person to walk normally up the stairs. Record the times in seconds in the data table.

⦁ Measure the time for each person to run up the stairs . Record the times in seconds in the data table.

Analysis

⦁ Calculate the total vertical height of the stairs in meters. Put your answer in the text box below:

⦁ Calculate the work done by each person in walking and running. In this case, the force would be the weight of the person and the distance would be the height of the stairs. Put your answers in the table below.

⦁ Calculate the power for each person in walking and running. Put your answers in the table below.

Conclusions

⦁ How does the work done in walking compare to the work done in running? Explain why you would expect it to be this way.

⦁ How does the power used in walking compare to the power used in running? Explain why you would expect it to be this way.

Write a short report on the 3 topics describing and explaining the Physics principles behind each chosen topic.

Write a short report on the 3 topics describing and explaining the Physics principles behind each chosen topic. In your report, you should refer to theories and laws. Your
explanations need to include words, equations, diagrams, tables, graphs and images. You do not need to include actual calculations – this assignment is based on analysis and critical thinking, not mathematical principles.

What is the generator current?What would the loss in power be?

Complete the following exercises:
Ch. 10: #14, Ch.11: #1,3. Question #14 deals with biofuel, while #1,3 deal with electricity distribution. Hints: for #1 you’ll need to incorporate Ohm’s Law and combine the definition of the area of a circle with info provided for wires.

Pics of 1, 3, 14 attached.

Additional questions from Dr. B :
#AB 1 If a single thermonuclear power plant produces 1,300 MW of electric power, and the generator voltage is 20kV, what is the generator current?
#AB 2 If the nuclear power plant transmitted its 1,300 MW electric power output over two 345 kV transmission lines with 1.5 Ω resistence, what would the loss in power be?
