Can you determine at what speed each is moving?// > **Question:** //Given the time at which the crafts coincide, how do we find the distance from the base?// > **Question:** //Can you draw the $x$ vs. $t$ and $v$ vs. $t$ graphs?// > **Question:** //What does the momentum principle tell you about the net force acting on each hovercraft? What evidence are you using to make the claim?// > **Question:** //Can you draw a motion map (momentum vector) for each hovercraft and explain how this motion maps relate to the graphs you drew?// > **Question:** //Why does each hovercraft fall for the same amount of time?// > **Question:** //Where does the formula $v_{f}^{2}=v_{i}^{2}+2ad$ come from?// ===Part 2=== > **Question:** What do you want the next addition of the code to do? > **Question:** Can you explain each important line in each while loop to me? > **Question:** Can you relate the position and momentum update lines in the code to analytical equations? > **Question:** What exactly is the motion map showing? > **Question:** Is there any change in the runaway cart's momentum, according to the code? > **Question:** Now can you add in the rescue cart? > **Question:** What is the difference between the runaway cart and the rescue craft code? > **Question:** //Could this job have been done by hand?// > **Question:** //What parts of the code don't you understand?// > **Question:** //Does the mass matter?// > **Question:** //How does the vertical net force change when moving from land to air?// > **Question:** //What about the air resistance? Can you add this in? Assume that it goes like $bv$ to make things easy.// 183_projects/learning_goals_project_2.txt Last modified: 2015/01/26 17:04by pwirving
