(a). It starts from rest, and its speed increases by 9.8 m/s every second. One tenth the speed of light is (1/10) (3 x 10⁸ m/s) = 3 x 10⁷ m/s . To reach that speed takes (3 x 10⁷ m/s) / (9.8 m/s²) = 3,061,224 seconds . That's about 35 days and 10 hours.
(b). Distance traveled = (average speed) x (time of travel) Average speed = (1/2) of (1/10 the speed of light) = 1.5 x 10⁷ m/s . Time of travel is the answer to part (a) above. Distance traveled = (1.5 x 10⁷ m/s) x (3,061,224 sec) = 4.59 x 10¹³ meters That's 45.9 billion kilometers. That's 28.5 billion miles. That's about 6.2 times the farthest distance that Pluto ever gets from the Sun.
The rocket ship takes approximately 3,061,224 seconds (about 35 days) to reach one-tenth the speed of light under constant acceleration of 9.8 m/s². During this time, it travels about 4.59 x 10¹³ meters, approximately 45.9 billion kilometers. This distance is equivalent to roughly 28.5 billion miles.
