Boxes are transported by a conveyor belt with a velocity v0 to a fixed incline at a, where they slide and eventually fall off at b. knowing that μk = 0.40, determine the velocity of the conveyor belt if the boxes leave the incline at b with a velocity of 14 ft/s.

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
