Homework Help: A Grade 11 Waves - Frequency-Movement Problem

  1. Nov 1, 2007 #1
    ****A Grade 11 Waves --- Frequency-Movement Problem****

    A 20g mass is picked up and moved from its rest position 20 cm. The mass has a frequency of 2.0 Hz.

    How far does it move in 10s. (Show work)

    I have no idea how to solve this. But if it helps I have learned these equations a day before my teacher gave me this Q to hand in tomorrow:

    f = N / T
    T = t / N
    V = WaveLength / T
    V = WaveLength * f

    What I tried was to solve it like this:

    f = N / T ----> 2 = N/10 -----> N = 20

    So x = 20 * 10 cm = 200 cm = 2 m

    Is it right? please answer ASAP. I have to hand this in tomorrow!
