Spring example problem

This video tutorial explains how to determine the total length of a spring with a 3 kg bucket of water hanging from it. It covers the properties of the spring, such as stiffness and unstretched length, and uses a free body diagram to identify forces acting on the bucket. By applying Newton's laws, the tutorial calculates the stretch of the spring and ultimately finds the total length when the bucket is attached.

What is the total length of the spring when a 3 kilogram bucket of water is dangling from it?

What is the spring stiffness K given in the problem?

What is the unstretched length of the spring?

What forces are acting on the bucket of water?

Explain how Hooke's Law applies to the spring in this problem.

How do you calculate the amount the spring has been stretched (X)?

What is the final calculated total length of the spring (L)?
