    Whats the equation for the coefficient of restitution again? Went blank!

    Code (Text):


    Coefficient of Restitution = Speed of Separation = v[sub]1[/sub]-v[sub]2[/sub]
                                 -------------------   -----
                                  Speed of Approach    u[sub]1[/sub]-u[sub]2[/sub]

    For the simple case of something bouncing off the floor (or any immoveable object) the coefficient of restitution is:

    c = vf/v0
    where v0 is the speed of the object before the collision, and vf is the speed after the collision.

    For perfectly elastic collisions, c = 1.

    It's like waiting for a bus, you have to wait for ages and then two come along at once.
