- Suppose you decide to travel to a star 85 light-years away at a speed that tells you the distance is only 25 light-years. How much is that speed?The crew of an enemy spacecraft attempts to escape from your spacecraft by moving away from you at 0.283 of the speed of light. But all is not lost! You launch a space torpedo toward the foe at 0.351 of the speed of light with respect to you. (a) at what speed in kilometers per second does the enemy crew observe the torpedo approaching its spacecraft? (b) Is this more or less than the classical limit? Use the Galilean transform to prove this. (c) What if the torpedo is launched at the speed of light? At what speed in kilometers per second does the enemy crew observe the torpedo approaching its spacecraft? (Show all work.) (d) How fast would the second craft have to be going to measure the torpedoes speed as 10% greater than the classical limit. (Assume the torpedo is launched at the original speed, 0.351 of the speed of light.)Explain the fact the special theory of relativity defines the limits for the validity of Newtonian mechanics.
- Can you prove Newtonian mechanics is a subset of special relativity?A 50-year-old astronaut goes off on a long-term mission in a spacecraft that travels at speeds close to that of light. The mission lasts exactly 200 years as measured on Earth. Biologically speaking, at the end of the mission, the astronaut's age would be exactly 25 years none of the above exactly 30 years O less than 50 years the same as beforeThe remaining lifetime of the Sun in seconds is 1.5 x 10¹7 sec. Convert this value into years. 0000000000000000 PLS HELP!
