Question
**Problem Statement:**

A thin rod extends from \( x = 0 \) to \( x = 16.0 \, \text{cm} \). It has a cross-sectional area \( A = 7.00 \, \text{cm}^2 \), and its density increases uniformly in the positive x-direction from \( 3.50 \, \text{g/cm}^3 \) at one endpoint to \( 19.0 \, \text{g/cm}^3 \) at the other.

**(a)** The density as a function of distance for the rod is given by \( \rho = B + Cx \), where \( B \) and \( C \) are constants. What are the values of \( B \) (in \( \text{g/cm}^3 \)) and \( C \) (in \( \text{g/cm}^4 \))?

- \( B = \underline{\hspace{1cm}} \, \text{g/cm}^3 \)
- \( C = \underline{\hspace{1cm}} \, \text{g/cm}^4 \)

**(b)** Finding the total mass of the rod requires integrating the density function over the entire length of the rod. The integral is written as follows:

\[
m = \int_{\text{all material}} \rho \, dV = \int_{\text{all } x} \rho A \, dx = \int_{0}^{16.0 \, \text{cm}} (B + Cx)(7.00 \, \text{cm}^2) \, dx
\]

What is the total mass of the rod (in kg)?
