In the best case scenario for a gravity boost, a spacecraft approaches a planet very closely and does a U-turn around it, heading back exactly in the direction it came (see the image below). Before Collision V After Collision If the spacecraft was initially going to the right with a speed of 3 km/s, and the planet was going to the left at a speed of 14 km/s, what would be the fastest the spacecraft could be going after the U-turn, in km/s?

Directions: Solve the following problems carefully. Write your detailed solutions on another sheet of paper.1. A spaceship, 200 m long as seen on board, moves by the Earth at 0.970c. What is its length as measured byan Earth-bound observer?2. Verify that the solution in Example 1 in the discussion is related through time dilation with γ = 30.00 as given
