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.
