Homework Statement

Homework Equations

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
