    Newton's Second Law - Polar Coordinates

    Alright so I think I finally have an answer! So my new force equations are: These forces act perpendicular to each other, so to find the net force of interaction you can use the Pythagorean Theorem. And like you said, the force of friction This gives me the equation Now all that was...

    Newton's Second Law - Polar Coordinates

    I'm not too sure how I would incorporate the weight in the force equation though. All I can really think of doing is: However this seems a bit strange to me because I can't see how the weight of the object would contribute to the forces in the direction of theta Also, I haven't used the fact...

    Newton's Second Law - Polar Coordinates

    Homework Statement Given that: theta_dot = 6 rad/sec m_A = 0.8kg u_k = 0.40 The problem also mentions that movement is at a constant angular rate so I think that means: r_doubleDot = 0 theta_doubleDot = 0 Lastly, at an instant: r_dot = 800mm/sec = 0.8m/sec 2. Homework Equations...
