Ablock (0.50 kg) is attached to an ideal spring with a spring constant of 80 n/m, oscillating horizontally on a frictionless surface. the total mechanical energy is 0.12 j. (a) what is the greatest extension of the spring from its equilibrium length? (b) now the block is traveling 2.00 m/s, and brought to rest by compressing a very long spring of spring constant 800.0 n/m. how much does the spring compress?

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
