Problem 20E
A 1.20-kg piece of cheese is placed on a vertical spring of negligible mass and force constant k = 1800 N/m that is compressed 15.0 cm. When the spring is released, how high does the cheese rise from this initial position? (The cheese and the spring are not attached.)

Problem 20E
A 1.20-kg piece of cheese is placed on a vertical spring of negligible mass and force constant k = 1800 N/m that is compressed 15.0 cm. When the spring is released, how high does the cheese rise from this initial position? (The cheese and the spring are not attached.)
ANSWER:
Solution 20E
Introduction
The potential energy of the cheese at the maximum height will be equal to the potential energy of the spring at maximum compression. Hence by calculating the potential energies we can calculate the maximum height of the cheese.
Step 1
The potential energy of the string, after compressing for amount x is given by
