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
