    Decibel Question (adding I think)

    Question at hand, A noisy machine in a factory produces a decibel rating of 80 dB. How many identical machines could you add to the factory without exceeding the 90 dB limit set by federal regulations? I just did a bunch of other problems regarding h/z and m/s and they were all right...

    Mechanical energy of a mass-spring system

    Wow I am stupid! KE= 1/2 290 N/m * (.026)^2 Thanks!

    Mechanical energy of a mass-spring system

    :bugeye: The chapter has been read very carefully by me twice. We haven't really covered mass at its maximum displacement, or maybe we have and called it something else. I think by maximum displacement you mean the amplitude which is ofcourse .026m. Maximum accel. is 15.08 m/s . I realize...

    Mechanical energy of a mass-spring system

    Thanks for the reply. I assume when you say pick a point you mean pick a point to plug in for the variable V. The amplitude is .026m So far I have this E=.25v^2 + 0.09802 Would V be 1/2 of the maximum acceleration?

    Mechanical energy of a mass-spring system

    Hey, Stuck on finding the mechanical energy of a mass-spring system, my question is as follows > A mass-spring system oscillates with an amplitude of .026 m. The spring constant is 290 N/m and the mass is 0.50 kg, it asks for the mechanical energy in (J). and the maximum acceleration of the...
