    How to interpret a Free Body Diagram for a Kite in Flight?

    The wind is blowing with a force of 48 N against a kite that Taylor is flying, so that the tail of the kite makes an angle of 24° to the ground. I am just really confused on this, I attacted the solution would anyone mind explaining it? I have no idea on how to get this

    Finding Force from the Potential Energy

    Ok Thanks so Much :) . I think it asking for it A, or else It would be asking for too much. I have to hand this question in. I already found a cubic equation and found the force to be 1.47N... but when I use a tangent line to find the force I get 1.66N. Which one do you think would be more...

    Finding Force from the Potential Energy

    The slope of the line at any given point, is the derivative of u(x) at that point. But seeing how the slope is constantly changing how would I estimate the Force. And what I was saying is that it looks like the graph can be modeled by a cubic equation. If I take 4 points off the graph, I can...

    Can I prove matrix properties using simple steps?

    [X, Y]= YX- XY Thus [Y, X]= XY- YX then -[Y, X]= -(XY- YX) then -[Y, X]= -XY +YX Like that? So i don't have to use matricies with variables, just use X and Y to represent a matrix?

    Acceleration using kinetic friction

    Part A: A block of mass M resting on a 18.8° slope is shown. The block has coefficients of friction μs=0.620 and μk=0.314 with the surface. It is connected via a massless string over a massless, frictionless pulley to a hanging block of mass 2.97 kg. What is the minimum mass M1 that will stick...

    Equilibrium Force Question Homework

    So sin57.1 + sin25.0 = 290N this would give me T1 and T2?

    Equilibrium Force Question Homework

    Okay I get that but I am not sure what to do next. You are saying that my T1 is 290N? I did figure out my T3 is 290N? How do I figure out T2?
