Question

A 100-N object sits on a rough floor and is being acted on by 150-N force that is directed 30° above the horizontal (i.e. someone is pulling upward while dragging it).   The coefficient of static friction is 0.5 and kinetic friction is 0.25.  

  1. Draw a free-body diagram for the object.
  2. Does the object move? Make your test clear.
