Calculating Spring Compression from Toy Car Collision

In summary, spring compression is typically measured in units of length and can be calculated by subtracting the length of the uncompressed spring from the length of the compressed spring. The amount of force applied, material and diameter of the spring, number of coils, and temperature can all affect the amount of compression. The spring constant can be calculated by dividing the force applied by the amount of compression, and finding the right amount of compression is crucial for the proper functioning of the spring. While spring compression can sometimes be adjusted after manufacturing, it is often more efficient to design and manufacture the spring with the desired compression in mind.

Homework Statement


A toy car with a mass of m=.079 kg crashes into a spring with constant k=69 N/m. If the car was going v=1.10 m/s, then how far will the spring compress?


Homework Equations


I think you could use the equation for Elastic Potential Energy but I'm not sure what to do with the mass or the velocity...

EPE= kv^2/2


The Attempt at a Solution


I really just don't know... I'm stuck and help would be greatly appreciated!

Check the units on your EPE equation. Are you getting Joules (energy)?
 

FAQ: Calculating Spring Compression from Toy Car Collision

How is spring compression measured?

Spring compression is typically measured in units of length, such as inches or millimeters. The amount of compression can be determined by subtracting the length of the uncompressed spring from the length of the compressed spring.

What factors affect spring compression?

The amount of force applied to the spring, the material and diameter of the spring, and the number of coils all affect the amount of compression a spring can achieve. Temperature can also impact the compression of a spring, as some materials may expand or contract with changes in temperature.

How do you calculate the spring constant for a compressed spring?

The spring constant, also known as the stiffness coefficient, can be calculated by dividing the force applied to the spring by the amount of compression achieved. The resulting value is the amount of force needed to compress the spring by one unit of length.

What is the significance of finding the right spring compression?

The correct amount of spring compression is important in order to achieve the desired function of the spring. Too much compression can cause the spring to fail or become permanently deformed, while too little compression may not provide enough force for the intended purpose.

Can spring compression be adjusted after the spring is manufactured?

In some cases, spring compression can be adjusted after the spring is manufactured by changing the number of coils or altering the material of the spring. However, it is often more efficient and cost-effective to design and manufacture the spring with the desired compression in mind.
