1. The problem statement, all variables and given/known data 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 2. Relevant equations For the second question I tried using the equation k = F_spring/delta s 3. 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?
