Homework Statement Find partial fractions for 4/(x^3-2x^2) The Attempt at a Solution Heres the steps that I took: 1. 4/(x^3-2x^2)= 4/(x^2(x-2))= A/(x^2) + B/(x-2) 2. 4= A(x-2) + B(x^2) 3. When x=0, -2A=4, so A=-2, and When x=2, 4B=4, so B=1. 4. So my final answer was: -2/(x^2)+1/(x-2) The...

So why is kinetic energy not conserved while momentum is conserved in a perfectly inelastic collision? Where does the kinetic energy go when the objects collide perfectly inelastically? Why does conservation of momentum happen? Is momentum a type of energy? Thank you for your help.
