Calculating Impulse on a Ball: Mass, Radius & Speed
Homework Statement Lets say I have a ball rolling on a flat frictionless surface. I give it an impulse to set it into rolling without slipping at a speed u. The mass of the ball is m and the radius is a. How large is the impulse and where is it applied Homework Equations I guess linear...- jeremy222

Undergrad Scaling Augmented Matrices: Is My Thinking Correct?
An augmented matrix scaled by a number also means the solutions set is scaled by that same number. I believe this is true due to it basically being the same as elementary row operations preformed on each row. Unless it is a zero scalar in which case you lose all conditions. Is my method of...- jeremy222
