As a horse pulls a cart, the force responsible for propelling the horse forward is the force applied by

Options

Athe ground on the cart
Bthe cart on the horse
Cthe horse on the ground
Dthe ground on the horse

Correct answer

D. the ground on the horse

Step-by-step solution

When a horse pulls a cart, it pushes the ground backward with its feet. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. The ground exerts an equal and opposite reaction force on the horse in the forward direction. This reaction force applied by the ground on the horse is responsible for propelling the horse forward.
