1) Based on this graph of force vs. extension for a certain spring, what should be the Hooke's law constant (or spring constant)
?
Show the full calculation using data from the figure, and report the answer in N/m.
2) Suppose a 250 g mass was hung from the spring in the previous question. What would be the extension of the spring when it is in equilibrium and at rest?
Write the equation needed to answer this question and the solve for the extension, recording the answer in either m or cm.
3) Now the 250 g mass hanging from the spring in the previous question is pulled down an extra 10 cm and released. What would be the period and the counting frequency of the oscillations?
Once again, begin with an equation and show the steps needed to find the answers.
