Homework Statement Homework Equations A = SDS-1 Under some specific conditions, An=SDnS-1 The Attempt at a Solution det(A-λI) = 0 (16-λ)(-λ) - (-64)(1) = 0 λ2 - 16λ + 64 = 0 λ = 8 Multiplicity 2. This is as far as I got because you need 2 eigenvalues to get 2...

Oh...Thanks! Previous problems like this had the second object initially at rest, so I used that way without thinking.

Homework Statement Object A of mass 10 kg moving at 10 m/s [E] interacts with (but does not touch) Object B of mass 8 kg moving at 12 m/s [N]. What is the minimum possible kinetic energy of the system after the collision? Homework Equations M1V1o + M2V2o = M1V1f + M2V2f KE = (.5)(m)(v2)...

EDIT: I figured it out by looking at this link pages 65-66. Thanks for looking though! http://www.bfasta.net/assets/files/departments/science/ismith/Phys%20446/Phys%20446%20Information/HSU/Chapter%204%20Acceleration.pdf Homework Statement Recently I just did a physics lab for kinematics in...

Homework Statement Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. Homework Equations y = x^2, x = y^2 about y = -1 The Attempt at a Solution I tried using both cylindrical and washer methods - but for...

Aha, thank you so much! :)

Homework Statement Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. Homework Equations y = \sqrt{x-1} , y = 0, x = 5; about y = 3 The Attempt at a Solution I already completed graphing it, but not really sure how...
