    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
    (a) The person outside of the car will see the car's velocity as being c/√2 and the baseball's velocity as c/√2, therefore the observer in frame S will see those two velocities as added together because they both move in the positive x-direction.
    (b) Car's velocity - ball's velocity = 0 *edit* now I think this answer might be -c/√2
    (c) I have no idea

    (a) so what did you do to get the answer, and what did you get ?
    (b) so what did you do to get the answer 0 and why do you now think it's wrong ?
    (c) which equations apply ?
