Question

Question 1 (Come) back to the future. Suppose that a father is 23.00 y older than his daughter. He wants to travel outward from Earth for 3.000 y and then back to Earth for another 3.000 y (both intervals as he measures them) such that he is then 23.00 y younger than his daughter. What constant speed parameter B (relative to Earth) is required for the trip? Number Units The number of significant digits is set to 4; the tolerance is +/-1 in the 4th significant digit

Answer 1

B suppose age of his daughter is g ox year before starting trip. : his age = (x+23) yers were earth after, trip age of daughter is (x+6) in (6 years) ea and his age will = 6+6-23) = 9-17) year. in est after completing his 6-years of trip. OXO 10 Then in earth's frame his age changes by OT = ((x-17) – (2 423) = 40 years. and in spaceship frame at = 6. years. Then accorbing to time delation OT = et ✓ I-B - 407 = B² = 12 & 18 = 0.988 unit no. unit
