    Proving a complex Force derivation with CalcConfused

    Homework Statement If we know F(t) the force as a function of time for straight line motion, Newton's second law gives us a(t) the acceleration as a function of time. We can then integrate a(t) to find v(t) and x(t). However, suppose we know F(v) instead. a) The net force on a body moving...

    Newton's Law question, Not sure if right

    Homework Statement [PLAIN]http://img208.imageshack.us/img208/9987/forcediagram.png In the figure above, two small objects (magnets for instance) of the same mass exert forces on each other of a magnitude F. When object A is subjected to an external force of 3.6x10^-2 N, A accelerates at...

    Axis Rotation and Vector magnitude problem not sure if answers are right

    Hey guys I'm sort of new to this forum, but I heard it was good so I thought i'd post a few questions hereHomework Statement The first question I have is not really a problem, but more of a question on the problem itself. I have two 3d vectors which are then subtracted to form a 3d vector in...
