I am stuck on how to start this question. Some hints should be enough to assist me. Here is the question:
Question: A football is thrown such that on release its axis of symmetry is10 deg above horizon and its angular velocity is 2.5 rev/sec (15.7rad/sec) at an angle 15 degree above axis of symmetry, the moment of inertia of the football about the axis of symmetry is 4/9times the moment of inertia about a perpendicular axis through its center of mass. Assuming torque free motion (N=0), find
Part A: Find the angle between symmetry axis of football and axis of precession?
Part B: Find the rate of precession?
Part C: Find the rate of spin?
I need help to find the angle between symmetry axis of football and axis of precession.
