Un cuerpo es lanzando verticalmente hacía arriba con una velocidad inicial de 30 m/s donde se desprecia la resistencia del aire ¿Cuál será la velocidad del cuerpo 2 segundos después de su lanzamiento?

¿Cuánto tarda el cuerpo en llegar al punto más alto de su trayectoria?

¿Cuál es la altura máxima alcanzada por el cuerpo?

According to the phase diagram for water, how is the state of water determined? proceed up a vertical line at any given temperature read the phase at the intersection of any given temperature and pressure at a given pressure, proceed horizontally to the s-l or l-g line

Stars x and y are both bluish main sequence stars. star x has a higher absolute brightness than star y. how do the two stars compare? explain

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.
