Homework Help: Average velocity

  1. Apr 12, 2005 #1
    A spring-mass system moves according to the position function x(t)=Asint. What is the average velocty in the period 0<=t<=2s?

    so the velocity is [tex]v(t)=A \omega cost[/tex]
    how would I calculate the average velocity?

    [tex]\frac{A \omega cost |^2_0}{2}[/tex] ??

    Definition for the average velocity

    [tex] \bar{v}_{T}=\frac{1}{T}\int_{0}^{T} v(t) \ dt [/tex]

    I get:
    [tex]\frac{\int_0^2Acost}{2}[/tex]
    [tex]\frac{Acos2-A}{2}[/tex]

    [tex]\int \cos t \ dt =\sin t +C [/tex]
