    HI! How do you get the answer to 5b? It was the question when you had show that when e = 0.4, there was another collision. I got that p was moving to the left and because Q had hit the wall and rebounded, that it was also moving to the left and said that q was moving faster than p so they will collide. Is this right or how many marks do you think i would get for this? How do you do it? It's really puzzling me.

    Thanks

    Prove that the velocity of Q is greater than the velocity of P.

    i.e. Vq > Vp

    If Q's velocity is greater than that of P's, and they're moving in the same direction, that means Q will catch up and collide with P.

    But did anyone else get q to be moving faster than P and that P and Q were moving in the same direction?

    Yeah that is exactly what you had to assume in part c) to get the range of values fo f.

    Part b on the other hand they were moving in opposite directions before Q hit the wall so the same direction in part c) after hitting the wall
