Let the zero of the potential energy be at x = 0 m.

what is the potential energy at x = 1.0, 2.0, 3.0, and 4.0 m?

hint: think about the definition of potential energy and the geometric interpretation of the work done by a varying force. express your answers using two significant figures separated by commas.

Which sound characteristic is not affected by the relative motion of an object

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
