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