Aircraft Trajectory Answers

You are the Copilot on a Boeing 747. The Captain plans to make various changes in speed. Let's assume that your aircraft is in simple aircraft motion with force and mass constant. As the Copilot you must be able to correctly tell the Captain what the results of these changes of velocity will be. Using the motion equations shown above solve for the unknown values to complete the following table. Assume that Xo is 0.
