Forces in a Climb - Vectors - Worksheet
  1. Using the first equation: L cos (c) + F sin (c) -D sin (c) - W = ma (vertical)
    and the third equation: F -D = Fex , explain and show how to obtain
    the fourth equation: L cos (c) + Fex sin (c) - W = ma (vertical).






  2. Using the second equation and the third equation, explain and show how to obtain the fourth equation.






  3.  Why isn't W multiplied by a sine or cosine?






  4. Using the given diagram, theorems/postulates of geometry, and vectors, explain each term in the first two equations.
