Question 9 of 10 - /1 IE Current Attempt in Progress An interstellar ship has a mass of 8.64 x 10 kg and is initially at rest relative to a star system. (a) What constant acceleration is needed to bring the ship up to a speed of 0.061c (where c is the speed of light, 3.0 x 10 m/s) relative to the star system in 4 days? (b) What is that acceleration in g units (enter the answer in the form N g, where N is a number)? (c) What force is required for the acceleration? (d) If the engines are shut down when 0.061c is reached (the speed then remains constant), how long (in s) does the ship take (from that point on) to journey 3 light-months, the distance that light travels in 3 months? Assume a month has 30 days. (a) Number Units (b) Number Units V (c) Number HI Units (d) Number Units
