Homework Statement
A 6.90 mass hanging from a spring scale is slowly lowered onto a vertical spring, as shown in the figure.
What does the spring scale read just before the mass touches the lower spring? --> I calculated this to be F= 67.6 N just using m*g.
The second question is:
The scale reads 24.0 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
The third question is:
At what compression length will the scale read zero?
delta y = ? cm
Homework Equations
For the second question I tried using the equation k = F_spring/delta s
The Attempt at a Solution
My attempted to use this formula to get k = 24 N/0.027 m which was equal to 888.9 N/m. However this is not correct. Can anyone tell me where I went wrong?
