Show that the girl at A can throw the ball to the boy at B by launching it at equal angles measured up or down from a 45° inclination. If vA = 10 m/s, determine the range R if this value is 15°, i.e., u1 = 45° − 15° = 30° and u2 = 45° + 15° = 60°. Assume the ball is caught at the same elevation from which it is thrown.
