A long thin rod lies along the x-axis from the origin to x=L, with L= 0.710 m. The mass per unit length, l (in kg/m) varies according to the equation l = l0 (1+1.110x3). The value of l0 is 0.300 kg/m and x is in meters.
Calculate the total mass of the rod.
Calculate the x-coordinate of the center of mass of the rod.
Calculate the moment of inertia of the rod with respect to the y-axis.

Because I'm thinking that if you're on the top floor, there isn't much that can fall on your head BUT it's a long way down. And the opposite will be true for the bottom floor. What do you think?

Mathematician states“Newton and Leibniz developed the calculus…. Their ideas were attacked for being full of paradoxes.” Newton’s formulation of calculus was self-contradictory yet it worked. Newton worked with small increments going of to a zero limit. Berkeley showed that this leads to logical inconsistency. the main problem was “that a quantity was very close to zero, but not zero, during the first part of the operation then it became zero at the end. That is one of the reasons this author says mathematics is meaningless
