researchers have measured the acceleration of racing greyhounds as a function of their speed; a simplified version of their results is shown in (figure 1). the acceleration at low speeds is constant and is limited by the fact that any greater acceleration would result in the dog pitching forward because of the force acting on its hind legs during its power stroke. at higher speeds, the dog's acceleration is limited by the maximum power its muscles can provide.
