Researcher have measured the acceleration of racing greyhounds as a function of their velocity; a simplified version of their results is shown in figure below. 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 muscle can provide. a. What is the agent of the force that causes the dog to accelerate? b.
