calculate mass of the wire

Hello

If anyone is able to help me with this problem, I would greatly appreciate it. Since this is also an even numbered question, im not able to look up the answer. Special thanks to Scott who helped me with the Stoke's Theorem problem.

Question:

A wire is formed to the shape of the curve r(t) = 2 t **i** + 4/3 t^(3/2) **j** + 1/2 t^(2) **k** , for 0<= t <= 1. The density of the wire at the point (x,y,z) is given by p (x,y,z) = 4 x z + 9 y^(2) grams per linear unit. Calculate the mass of the wire.
