Mammals that depend on being able to run fast have slender lower legs with flesh and muscle concentrated high,? close to the body. on the basis of rotational dynamics, explain why this distribution of mass is advantageous.

The longer and slimmer an animals legs are such as a horse, have larger amounts of muscle mass in their upper portion of leg such as the thigh and glute muscles. The glute being larger and the thigh gives the muscles more power distributed to the lower legs to propel large amounts energy to the limbs creating fast motion.
