Angular Equations: Examples • A disk rotates about its central axis starting from rest at t = 0 and accelerates with constant angular acceleration. At one time it is rotating at 4 rev/s; 60 revolutions later, its angular speed is 16 rev/s. Starting at t = 0, what is the time required to complete 64 revolutions? Answer: t .

F M = 1 2 C L 2Av, 2 where A is the cross sectional area of the ball, v is its speed, is the air density kg/m, and C D and C L are the drag and lift coefficients, We will focus only on C L. Data on other spherical sports balls suggest that C L is mainly a function of the spin factor S=R /v, although it may also be a function of the Reynolds number Re=2 Rv/ .2,16 Here
S c =/d, where d is the inside diameter of the grinding chamber in feet, where critical speed (S c) is in rpm. In particular, the cylinder is rotated about its longitudinal axis at 5080% of critical speed (S c). In preferred embodiments, the cylinder is rotated at 7375% of the critical speed.

The full body swing generates greater ball speed, which is important for the golfer. The full body swing is more efficient. The amount of energy produced in the full body swing is created by 4 muscle groups instead of 2. The arm swing relies on 2 muscle groups, both which are smaller than any of the 4 muscles in the full body swing.
