I hope this helps . , You're missing a paren on this line:
code :
t = np.linspace( start,end,n+1,dtype=np.float(64)
t = np.linspace( start,end,n+1,dtype=np.float(64))

I think the issue was by ths following , Coefficient of restitution has to do with the relative elasticity of the colliding objects. It's a simplisitic way to account for the fact that the ball and the surface both deform on impact. Some of the energy of deformation is lost (e.g. generated heat, sound waves, etc.), but most of it goes back into "pushing" the other body away.
None of the energy is lost if the coefficient of restitution equals 1.0. Think of it as a "fudge factor" so you don't have to do a dynamic elasticity problem.

it fixes the issue This is a well-known artifact of the algorithm you're using to integrate the movement's differential equation.
The "real physics" is (I will only discuss the y component)

hop of those help? One way you could approach this is to not extend BallImpl, but make sort-of plugins. Like this:
code :
public class BallImpl implements Ball {
    List<BallBehavior> behaviors = ...

    @Override
    public void update() {
       behaviors.forEach(behavior -> behavior.update(this));
    }
    ...
}

public interface BallBehavior {
    void update(BallImpl ballImpl);
}

fixed the issue. Will look into that further I should start by saying: I created a new answer because I feel the old one has value for its simplicity
as promised here is a much more complex physics engine, yet I still feel it's simple enough to follow (hopefully! or I just wasted my time... lol), (url: http://jsbin.com/otipiv/edit#javascript,live)

seems to work fine When you pass the int into the translate method it is 'by value', not 'by reference' so any changes you make to the value will not last beyond the scope of the method.
You need to do the the check of y, and the reversal of it, higher up in your code, likely in the same method where you are calling translate from.
