I have been trying for days. You can even just give me 2 lines- please, I need something to work with. Peter's parents told him that for every 5 hours of homework or reading he completes, he will be able to play 3 hours of video games.

If you have looked at the list of solutions to the equations of motion we derived in the preceding section, you will have discovered that they look horrible. Unless you have a great deal of experience with visualizing equations, it is extremely difficult to work out what the equations are telling A Java applet posted at http: The applet will open in a new window so you can see it and read the text at the same time.

The applet simply calculates the solution to the equations of motion using the formulae given in the list of solutions, and plots graphs showing features of the motion. Note that you can control the properties of the spring-mass system in two ways: The steady state response of a forced, damped, spring mass system is independent of the initial conditions.

You will see that, after a while, the solution with the new initial conditions is exactly the same as it was before. Change the type of forcing, and repeat this test. You can change the initial velocity too, if you wish.

The transient response depends on everything… Now, reduce the damping coefficient and repeat the test.

You will find that the system takes longer to reach steady state. Thus, the length of time to reach steady state depends on the properties of the system and also the initial conditions. The observation that the system always settles to a steady state has two important consequences. When analyzing forced vibrations, we almost always neglect the transient response of the system, and calculate only the steady state behavior.

If you look at the solutions to the equations of motion we calculated in the preceding sections, you will see that each solution has the form Following standard convention, we will list only the steady state solutions below.

You should bear in mind, however, that the steady state is only part of the solution, and is only valid if the time is large enough that the transient term can be neglected. This section summarizes all the formulas you will need to solve problems involving forced vibrations.

Solved: Write and absolute value equation that has the given solutions of x=3 and x=9 - Slader/5(1). amplitude: The maximum absolute value of some quantity that varies, especially a wave. In physics, interference is a phenomenon in which two waves superimpose to form a .

So a positive and a positive wave function create a bonding orbital where the probability of finding an electron is summed while a positive and a negative create an anti-bonding orbital with a lower electron probability in the region between them leading to a repulsion.
