(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A rod of length 38.5 cm has linear density (mass-per-length) given by the following equation, where x is the distance from one end.

λ=50.0g/m+16.5g/m^2

a. What is its mass in g?

b. How far from the x=0 end is its center of mass in m?

2. Relevant equations

3. The attempt at a solution

For part a., could I just divide by the mass?

Could someone please show me how to do this problem? I really don't understand what it's asking for.

Thank you very much
