Abstract: The present invention encompasses a golf ball having a diameter and being comprised of a core and a cover, wherein the core is further comprised of a fluid mass at the center of the ball, and a first, solid, non-wound mantle layer surrounding the fluid mass, wherein the first mantle layer comprises a copolymer or terpolymer of ethylene and an ?,?-unsaturated carboxylic acid, the acid being neutralized at least 80% by a salt of an organic acid, a cation source, or a suitable base of the organic acid, and wherein the cover comprises polyurethane, polyurea, or a polyurea/polyurethane hybrid. Preferably, the rate of spin decay is at least 10% of an initial spin rate of the golf ball over the entire ball flight.

Abstract: An apparatus and method for testing the physical properties of a material is disclosed. Preferably, the physical properties that may be tested include, but are not limited to, the COR of a material. Accordingly, the apparatus includes a projectile that may be capable of being propelled towards a material sample. The projectile is preferably aimed and fired through a tubular barrel towards the material sample. The tubular barrel preferably comprises a propulsion system that controls pneumatic energy via a pneumatic valve. At least two sensors are placed between the tubular barrel and the material sample in order to detect the passage of the projectile. It is desired that the sensors are placed at precise, discrete positions. As the projectile passes through the field of view of each sensor, the time is recorded to a memory, for example, a counter timer board. The projectile may then impact the material sample, which may preferably be held in place by a fixation device.
