A 8.2 kg mass hanging from a spring scale is slowly lowered onto a vertical spring.

Part A: What does the spring scale read just before the mass touches the lower spring?

Part B: The scale reads 28N when the lower spring has been compressed by 2.5cm. What is the value of the spring constant for the lower spring?

Part C: At what compression length will the scale read zero?
