Un bloque de madera, con una densidad de 710Kg/m 3 y un volumen de 0.012m 3 , está unido al extremo de un resortevertical cuya constante de fuerza es K= 540N/m. Encuentra que tanto se estira el resorte.

The force will determine the acceleration.

An engineer designs a roller coaster so that a car travels horizontally for 152 ft, then climbs 137 ft at an angle of 34.0° above the horizontal. it then moves 137 ft at an angle of 48.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

When does your body conduct current more readily?
