1. A boy stands out at the end of the diving board, which is supported by two springs A and B, each having a stiffness of k = 15 kN/m. In the position shown the board is horizontal. If the boy has a mass of 40 kg, determine the angle of tilt which the board makes with the horizontal after he jumps off. Neglect the weight of the board and assume it is rigid.
