Dos bloques de masa 0,5kg cada uno se mueven hacia la derecha con velocidades de 2 m/s y 1 m/s inmediatamente antes del choque, el que se mueve a 2 m/s va detrás del que se mueve a 1 m/s. Si, después del choque, el que iba a 2m/s reduce su velocidad a la mitad , ¿con qué velocidad se mueve el otro?

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?

Afisherman notices that his boat is moving up and down periodically without any horizontal motion, owing to waves on the surface of the water. it takes a time of 2.20 s for the boat to travel from its highest point to its lowest, a total distance of 0.670 m . the fisherman sees that the wave crests are spaced a horizontal distance of 5.80 m apart. (a) how much is the wavelength? (b) find the period of the wave. (c) how fast are the waves traveling? (d) what is the amplitude a of each wave?

Which of the following best describes the circuit shown below?
