Una fuerza de 1.70N actúa sobre un deslizador de 0.4kg de tal forma que lo hacelera a lo largo de un fiel de aire. La trayectoria y la fuerza siguen la misma linea horizontal. ¿Cuál es la rapidez del deslizador después de acelerar desde el reposo a lo largo de 50cm, si la fricción es despreciable?

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)

Sound travels slower in colder air that it does in warmer air. make a claim about the effect of air temperature on the speed of sound. support your claim with evidence
