An 8-kg plunger is released from rest in the position shown and is stopped by two nested springs; the constant of the outer spring is k1 = 3 kN/m and the constant of the inner spring is k2 = 10 kN/m. If the maximum deflection of the outer spring is observed to be 150 mm, determine the height h from which the plunger was released.
