A frisbee in flight has lift and drag coefficients of CL and CD, respectively, where the reference area, A, is the frisbee (planform) area. The mass of the frisbee is m and the gravitational acceleration is g.
a) Shetch the free body diagram for the frisbee during level flight, i.e., identify all of the horizontal and vertical forces acting on the frisbee.
b) Label the horizontal and vertical directions as x and y, respectively, and label the corresponding (frisbee) accelerations as x ̈ and y ̈. Write down the equations of motion (i.e., write Newtonâ€TMs second law) for the frisbee in both the horizontal and vertical directions.
c) Consider the case where the frisbee is released from a height ho, with a purely horizontal intitial velocity, vo. Neglecting the (relatively weak) lift force, calculate how long it takes for the frisbee to hit the ground.
