As the shopping trip progressed, the cart increased in mass from 0 kg to 10 kg. Which argument below supports Raymond's claim that it was more difficult to push the 10 kg cart as opposed to the empty cart. O As the cart decreased in mass, Raymond had to use more force to push the cart. O As the cart increased in mass, Raymond had to use more force to push the cart. O As Raymond continued to push the cart during the duration of the trip, he became tired which made it more difficult to push the cart. O As Raymond continued to push the cart during the duration of the trip, friction began to build up on the wheels causing the cart to be more difficult to push.
