Yes
No
Imagine Aiden and Jackson are at the top of a hill with a shopping cart. Aiden gives the cart a gentle push, and it starts rolling down towards the parking lot. Which of the options below best supports your reasoning about what happens next?
The cart would slow a bit more, but then move at a constant speed across the parking lot. The car is what stopped it and is the only thing that could have stopped it.
The cart slows down since its kinetic energy is being converted to thermal energy, because of the friction present on the parking lot. It would have eventually slowed to a stop regardless of whether there was a car in the way.
The speed of the cart would always be increasing after the man releases it. The car stopped it because it was in the way, otherwise the cart would continue to speed up.
The cart slows down because its kinetic energy is disappearing. It would slow to a stop regardless of whether there was a car in the way.
