Hmm it makes sense that the density is not constant. But I don't understand how I am supposed to solve that integral. If mass=\int(p)dV, and p = 7800-360(z/L)2, "z" can be any number between 0 and 2. Also the integration is with respect to V, which is not in the given density formula. Thanks...

This is one of my homework problems for my mechanical engineering class. The problem is extremely simple, but, the homework is graded in this class and I want a good grade :). I should be able to do this no problem but I am getting confused by what some of the reading in my book is telling me...

Wow that makes much more sense now, thanks a lot!

Homework Statement A) A ball with a mass of .360kg is dropped from a height of 1.20 meters above the top of a fixed vertical spring, whose force constant is 350 N/m. What is the speed of the ball when the spring has been compressed 5.0cm? (Ignore the mass of the spring; also, notice that...
