1. A person is pulling a heavy cart up a hill. The cart has 400 kg of mass inside it. The person is pulling the cart with 10 N of force. What is the magnitude of the force on the person due to the cart?


3. Is it 4000N?

What does Newtons third law say about people exerting a force on a cart?

What does Newtons third law say about people exerting a force on a cart?

For every action there is an equal and opposite reaction.

 

[CWatters]

Correct.

The question states that the person exerts a force of 10N on the cart so apply Newtons third law to work out how much force the cart exerts on the person.
