    I agree with a, b, and c1.

    I'm not sure about c2, it might be correct. I would have used the relativistic velocity-addition formulas.

    When I used to work out these kinds of problems, I would write down values of any gamma factors I calculate along the way. That saves time, not having to recalculate it when they often get used repeatedly. It's also an intermediate check, when I'd end up with a wrong answer and am tracking down where the mistake was.

    Yea. Velocity transformation is another way of doing it. But the answer is different. Why I cant use time dilation to calculate the relative time taken for the ball to travel in this case?
