# Explain Why A Horse Cannot Pull a Cart and Run in Empty Space - CBSE (Science) Class 11 - Physics

ConceptCommon Forces in Mechanics

#### Question

Explain why a horse cannot pull a cart and run in empty space

#### Solution 1

In order to pull a cart, a horse pushes the ground backward with some force. The ground in turn exerts an equal and opposite reaction force upon the feet of the horse. This reaction force causes the horse to move forward.

An empty space is devoid of any such reaction force. Therefore, a horse cannot pull a cart and run in empty space

#### Solution 2

A horse by itself cannot move in space due to law of inertia and so cannot pull a cart in space.

Is there an error in this question or solution?
