Anew spacecraft is built with an engine that is able to produce constant acceleration of 1g, where g = gravity’s acceleration on earth = 10m/s^2. a) calculate how long it would take the starship to reach a velocity of 0.9c where c is the speed of light. b) calculate how far the spaceship would travel during this time and compare this to our nearest neighbor in space, alpha centauri

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
