You have an apple that you would like to weigh, but you don’t have a scale. You do have a slinky and a quick internet search tells you that it has a spring constant of 10.0 N/m. You hang the apple from the slinky and measure that the slinky stretches 9.92 cm. What is the mass of the apple?
People who ride motorcycles and bicycles learn to look out for bumps in the road and especially for washboarding, a condition in which many equally spaced ridges are worn into the road. What is so bad about washboarding? A motorcycle has several springs and shock absorbers in its suspension, but you can model it as a single spring supporting a block. You can estimate the force constant by thinking about how far the spring compresses when a heavy rider sits on the seat. A motorcyclist traveling at highway speed must be particularly careful of washboard bumps that are a certain distance apart. What is the order of magnitude of their separation distance?
A typical mattress has a network of springs that provide support. If you sit on a mattress, the springs compress. A heavier person compresses the springs more than a lighter person. Use the properties of springs and spring forces to explain why.

- Car enthusiasts often lower their cars closer to the ground as a matter of style. James wants to lower his car by replacing all four of his original coil springs with new ones offered as an option by the car manufacturer.
