The figure shows a football in three common in-flight configurations. Case (a) is a perfectly thrown spiral pass with a spin rate of 130 rev/min. Case (b) is a wobbly spiral pass again with a spin rate of 130 rev/min about its own axis, but with th through a total angle of 16°. Case (c) is an end-over-end place kick with a rotational rate of 130 rev/min. For each case, specify the values of p, 6, B, and as defined in this article. The moment of inertia about the long axis of the ball is 0.27 transverse axis of symmetry. 16 (a) (b) (c)
