Question 1. A 6.30 kg mass hanging from a spring scale is slowly lowered onto a vertical spring, as shown in figure:
A. What does the spring scale read just before the mass touches the lower spring?
F = __ N
B. The scale reads 16.0 N when the lower spring has been compressed by 2.70cm. What is the value of the spring constant for the lower spring?
k = __ N/m
C. At what compression length will the scale read zero?
Δ y = __ cm
