QUESTION 1 (7.5 marks) An 8 kg plunger in Figure 1 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. It is observed that the inner spring is 90 mm shorter than the outer spring and when the plunger strikes the springs, the maximum compression of the outer spring is observed to be 150 mm. a) Using the principle of work and energy, determine the height h from which the plunger was released.
