    Using Momentum, KE and PE to solve this skier velocity problem

    That was my conclusion.

    Using Momentum, KE and PE to solve this skier velocity problem

    m*g*h=(1/2)*m*v^2 v=sqrt(2gh) Fg=Fc g=(v^2)/r g=(2gh)/r r=2h 32.8=2h h=16.4

    Using Momentum, KE and PE to solve this skier velocity problem

    Ah, centripetal force? That makes the height, ##h##, 16.4m. I did not think about this. I will review centripetal force. Thank you.

    Using Momentum, KE and PE to solve this skier velocity problem

    Gravity is the only force acting on the skier, so the acceleration is ##-9.81m/s^2##.

    Using Momentum, KE and PE to solve this skier velocity problem

    ##V=sqrt(2*g*h)##, where h is the height shown in the picture. The skier would lose contact with the snow if there still is momentum in the y direction right when they reach the crest of the second hill. Or, if the momentum in the y direction reaches 0 just as the crest is reached.

    Using Momentum, KE and PE to solve this skier velocity problem

    See a picture of the question above. My thoughts are: dp(y)/dy is negative such that when going up the slope, the momentum in the y direction is equal to 0 just as the skier reaches the top of the circular section. Given that there is no friction on the slopes, the energy of the skier...

    Thank you.

    How do PI controllers achieve steady state?

    I suppose then that the modern approach is to develop a transfer function with the poles and zeros needed to insure stability for the anticipated operating conditions. Is that correct?

    How do PI controllers achieve steady state?

    Hello DaveE, Would you happen to have any documentation on second order integrators in PID controllers? Thank you for your explanation.

    How do PI controllers achieve steady state?

    Summary: A question about how PI controllers reach steady state Hello PhysicsForums, I need a little help understanding how a PI controller works when operating in steady state. Here is the equation in State Space form: Where In standard form, the equation is: Where The question I’m...
