A tennis ball is released at rest vertically from an initial height of h0 on the rigid ground. The maximum height that the tennis ball can reach after its third rebound from the ground is h3, determine the h0/h3 ratio if the coefficient of restitution between the tennis ball and the rigid ground is e = 0,76 (g = 10 m/s2). Note: Please answer with 2 digits after the comma! h0/h3 = ?
