Inclined projection motion (flight trajectory)

Beginning status (before activation):

   1 *
   2 *Inclined projection motion (flight trajectory)
   3 *Initial velocity v0=14 m/s  Acceleration due to gravity g=9.81 m/s^2
   4 *Initial angle A=40(5)50 degrees  (i.e. 40, 45, and 50 degrees)
   5 *
   6 *Initial angle in radians a=A/360*2*PI  PI=3.141592653589793
