- 1. If the velocity of your spaceship goes from 0.3c to 0.6c, then your mass will increase bya. 19%b. 38%c. 74%d. 100%e. 200%4. A lkg mass initially at rest is accelerated by a 30N force, continuously, for a full year. How fast is it going at the end of that year? (If your answer is larger than the speed of light, you've done something wrong!). Hint: F = Ap/At.00 How long does it take (in seconds) for light to travel from the Sun to Saturn if the Sun is roughly 1.5 10^9 km away and the speed of light is 3*10^8 m/s?
