Question

 A box of mass m = 0.12 kg is set against a spring with a spring constant of k1 = 595 N/m which has been compressed by a distance of 0.1 m. Some distance in front of it, along a frictionless surface, is another spring with a spring constant of k2 = 158 N/m. The box is not connected to the first spring and may slide freely.


 How far, d2 in meters, will the second spring compress when the box runs into it? 

How fast, v in meters per second, will the box be moving when it strikes the second spring? 

Now assume that the surface is rough (that is, not frictionless). You perform the experiment and observe that the second spring only compresses a distance d2/2. How much energy, in joules, was lost to friction? 



The image illustrates a mechanical system consisting of a mass (denoted as \(m\)) situated on a horizontal surface. The mass is connected to two springs, one on each side, that are attached to vertical walls. The setup is within a coordinate system where the x-axis is along the horizontal direction, and the y-axis is vertical. An arrow indicates that the mass is moving to the right along the x-axis. 

This configuration describes a classic physics problem involving oscillatory motion, where the mass \(m\) can move horizontally, compressing and extending the springs as it moves. The springs are likely to follow Hooke’s Law, which states that the force exerted by a spring is proportional to its displacement from the equilibrium position and is directed opposite to the displacement.

This type of system can be used to study simple harmonic motion, damping effects if friction is introduced, and resonance phenomena under external periodic forces. Key parameters of interest in such a study include the spring constants, the mass of the block, and any frictional forces present.
