Which sentence is a correct statement of Newton's second law?
An object in motion stays in motion, and an object at rest stays at rest unless acted upon by a net force.
Every mass in the universe is attracted to every other mass in the universe.
Every action has an equal and opposite reaction.
When an object experiences a net force, it will accelerate at a rate determined by its mass.

Assume you measured the mass of the cart to be (500 ± 1) g and the mass of the additional mass you put on the cart to be (500 ± 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
