    Frequency of Vibration for a Block Supported by Two Springs

    Homework Statement A block of mass m is supported by two identical parallel springs, each with spring stiffness constant k. What will be the frequency of vibration? Homework Equations f = 1/[2*pi*sqrt(m/k)] The Attempt at a Solution I am just curious how the fact that there are two springs...

    If f(2) = 3 and f ' (2) = -1, then what is f(x)

    Thanks for the fast replies! I haven't learned integration yet. So then how do you propose I do this question. (Actual HW question) Given: g(2) = 3 g'(2) = -2 h(2) = -1 h'(2) = 4 f(x) = g(x)/h(x) Find f'(2)

    If f(2) = 3 and f ' (2) = -1, then what is f(x)

    This is more of a generic question...but it's shown up in so many of my homework questions that I thought I would consult the pros at PF. If I am given...let's say: f(2) = 3 f'(2)= -1 How would I go about finding f(x) Thanks in advance. :rolleyes:

    Solve Tension Problem: 1000kg Mass at 1m/s^2

    Net force. I think it's option B that I did in my first post.

    Solve Tension Problem: 1000kg Mass at 1m/s^2

    That the acceleration of an object is directly related to force and inversely related to mass. Basically F=ma I guess.

    Solve Tension Problem: 1000kg Mass at 1m/s^2

    Homework Statement Tension on the rope to pull a 1000kg mass up at 1m/s^2 Homework Equations F=ma The Attempt at a Solution I'm not sure. It's either A. T=ma T=1000(1)=1000 N or B. T-mg=ma T-(1000)(10)=(1000)(1) T=11000N Thanks.

    High School As the waves travel through a medium, they lose velocity

    Thanks for the help guys, but I don't get how a wave can have a constant velocity...if it eventually stops moving.

    High School As the waves travel through a medium, they lose velocity

    as the waves travel through a medium, they lose velocity, however the frequency is constant right? thanks
