A customer enters a grocery store with an empty shopping cart that has a
mass of 20 kg. Another customer is leaving the store with a shopping cart
full of groceries that has a mass of 40 kg. The two customers accidentally
bump their carts together. Eve observes the accident. She hypothesizes
that the cart full of groceries applied more force to the empty cart than
the empty cart applied to the full cart. Explain whether you agree or
disagree with Eve's hypothesis. Use Newton's third law of motion to
support your answer.
