Question

I'm stuck on how to start this problem. Some hints should beenough to help me.

Here is the problem:

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 deg above axis of symmetry. Themoment of inertia of the football about the axis of symmetry is 4/9times the moment of inertia about a perpendicular axis through itscenter of mass. Assuming torque free motion (N=0), find a)angle between symmetry axis of football and axis of precession, b)rate of precession, and c) rate of spin.

Explanation / Answer

plss increase points and comment hre again plsss and rate it plss
