Question;

Find the center of mass, and the moments of inertia and radii of gyration about the coordinate axis of a thin wire lying along the curve

r(t)=ti + (2sqrt(2)/3)t^(3/2)j + (t^2)/2k t between 0 and 2

if the density = 1/(t+1)

-Is this r(t) equation the parametric equation?
-When you calculate the Mass=integral of the density function ds ... are the limits of integration just from 0 to 2
