Erklärungen zu den Variablen:
w1/w2: Punkte der Wand
xp/yp: X-Position bzw. Y-Position

b: Ball(vektor)
w: Wand(vektor)
xv/yv: X- bzw. Y-Wert des jew. Vektors vom jew. Objekt
fx/fy: X- bzw. Y-Wert des finalen Ballvektors

Formeln:
w.xv = w2.xp-w1.xp
w.yv = w2.yp-w1.yp
nx = (-w.yv / sqrt(w.xv * w.xv + w.yv * w.yv))
ny = (w.xv/ sqrt(w.xv* w.xv+ w.yv* w.yv))
fx= - (2 * (nx* b.xv+ ny * b.yv) * nx - b.xv)
fy= - (2 * (nx * b.xv + ny * b.yv) * ny - b.yv)
