    You should be alright! Just keep positive Even if the paper is awful, grade boundaries will reflect that!

    on the last question, how can you be sure to assume the direction of Q is reversed by the collision? (part b)

    wait forget that, how do you get the speed of separation as v+w because I did v-w

    Well you know the speed of P after it's hit the hall and you know what speed Q is moving towards it, you know the coefficient of restitution between the particles so you can work out the speed of P after the second collision and find out whether it's reversed or not.

    it depends on what way you took as your positive direction and which direction you assume the particles move in after the collision.

    I thought if particles were moving away from each other you minus the faster from the slower?

    It they were moving away, like in opposite directions then you + them

    v - - w = v + w
