Un coche se lanza desde el suelo a 12.0 m/s, directamente hacia arriba. el cohete se mueve con velocidad constante vertical hasta que su combustible se agota en 6.00 segundos. luego cae libremente hasta chocar con el suelo. a)calcular el tiempo total que el cohete permanece en el aire. b) la altura máxima que alcanza el cohete, desde el suelo. c) el recorrido total del cohete mientras está en el aire

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.)

Explain earth's motion, using the terms "precession" and "rotation" in your answer.
