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 owl dives toward the ground with a constant velocity of 4.40 m/s at 53.0° below the horizontal. the sun is directly overhead and casts a shadow of the owl directly below it. what is the speed (in m/s) of its shadow on level ground?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.

If the pressure in a gas is doubled while its volume is held constant. true or false
