Una bola de playa con una masa de 0.06 kg es lanzada hacia arriba a una velocidad de 6m/s y al bajar cae en una caja y se detiene en 0.04 s. Determina el momentum y la fuerza media que ejerce la caja sobre la bola

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a

Total solidification times of three casting geometries are to be compared: a sphere, a cylinder, in which the length-to-diameter ration - 1.0, and a cube. volume = 1000 cm^3 for all three shhapes, and the same casting alloy is used. a) determine the solidification times of each geometry b) based on the results of part (a), which geometric element would make the best riser? c) if the mold constant = 3.5 min/cm^2 in chvorinov's rule, compute the total solidification time for each casting.

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
