    Static friction on an inclined plane.

    Homework Statement http://img124.imageshack.us/img124/9997/problem3.jpg Homework Equations f=mgcos theta The Attempt at a Solution I am thinking the answer is f = mgcos theta because gravity only acts on y-component but the answer is f=mgsin theta . Can anyone explain?
  3. M

    Two objects of different masses slide up an inclined plane.

    The heavier object has more K.E due to more mass , so it has more P.E and i guess more height?
