Suppose a spaceship is flying past me, an observer on earth, at .86c. A traveler on the ship has a ball which is attached to a string which is 100 feet long in the ship frame. The traveler grabs the string and throws the ball out of the front window of the ship at a speed of 100 feet per second in the ship frame. Are the following calculations correct?:
1. In my frame of reference the ball is gaining distance on the ship at 50 feet per second.
2. In my frame of reference, when the string is fully extended, it is 50 feet long.
