Homework Statement A cutting tool under microprocessor control has several forces acting on it. One force is \vec{F}=-αxy2\hat{j}, a force in the negative y-direction whose magnitude depends on the position of the tool. The constant is α=2.50 N/m3. Consider the displacement of the tool from...

That makes sense. Thanks.

here's a re-upload if that one's hard to see

Is the free body diagram I've attached right?

I have a question for two scenarios (see the diagram attached): 1) When the two blocks on the table are at rest, the static friction the table exerts on the bottom block is counteracting the tension in the rope, resulting in a net force of zero. Is there any static force being exerted by the...

Oh wow. That was pretty simple in retrospect... thanks.

Homework Statement You drop a baseball from the roof of a tall building. As the ball falls, the air exerts a drag force proportional to the square of the ball's speed (f=Dv2). (a) In a diagram, show the direction of motion and indicate, with the aid of vectors, all the forces acting on the...
