ANSWER:
Part (a)
Step 1 of 6:
A horse is standing on the ground and two forces acting on each foot of the horse. The center of gravity of the horse is located in the middle of the feet. We are going to find the value and the direction of the force.
The mass of the horse with the rider
The acceleration due to gravity
The distance between the ground and center of gravity
The distance between the ground and the point where frictional force is felt
The distance between the center of gravity and the middle of the feet
There force on each foot is the resultant force of the half of the frictional force acting on the wall and the half of the weight of the horse with the rider.
