Final answer:
A horse stands on four feet or hooves, and each hoof supports a certain amount of weight. To determine how many feet the horse stands on, we divide the total weight by the weight supported by each hoof.
Step-by-step explanation:
The horse stands on four feet, so-called hooves. Each hoof is responsible for supporting a certain amount of weight. To find out how many feet the horse stands on, we need to divide the horse's weight by the weight supported by each hoof.
Given that the horse stands at 63 inches or 5.25 feet, and the total mass of the horse and rider is 500kg, we can calculate the magnitude and direction of the force on each foot of the horse in Figure 9.32 by considering the equilibrium of forces acting on the horse.
Since the horse has four hooves, we divide the total weight by four to obtain the weight supported by each hoof: 500kg / 4 = 125kg.
Therefore, the horse stands on four feet or hooves that each support a weight of 125kg.
