    Express 3x3 matrix as projection + shearing

    Homework Statement Think of the following matrix A = \left( \begin{array}{ccc} a & b & c \\ d & e & f \\ g & h & i \end{array} \right) as a transformatiom of \mathbb{R}^3 onto itself. Describe A as a projection onto a plane followed by a shearing motion of the plane. 2...

    Classical Mechanics - Pulleys System

    Homework Statement Consider the pulleys system in the picture. Assume both pulleys are frictionless. Assume the rope is massless and inextensible. Find the acceleration of the mass m_2 Homework Equations The Attempt at a Solution I have solved the same problem with massless...
