Homework Help: Intermediate Mechanics

  1. Aug 27, 2010 #1
    We're in the first chapter - Matrices, Vectors, and Vector Calculus. I'm not sure why I'm having trouble. I got an A in Vector Analysis in the spring. :frown: I think some of the notation is throwing me off for some reason.

    I know a bold letter represents a vector, but what about the italicized letter? Is it the norm of the vector or simply a scalar? Please, check my notation carefully and my work. I apologize for the blurry picture. I'm having to use my camera phone right now as I haven't moved my multi-function printer to the new house.

    26. Haven't got a damn clue.

    28. I think I'm close to the right solution, but I still need clarification on some things.

    31. I started (a) and (c).
