Hello Mr Speranza. For question 4, I didn't use the vector equation of a line, instead I found the unit direction vector and multiplied by the magnitude of vb to get the vector vb, then integrated and subbed in t = 0, rb = Q, to get rb, then equated components of ra and rb to find the times of collision. Would this still be a valid solution? (I got the same answer). Thank you very much.
