True and false

  1. Mar 16, 2008 #1
    1. The problem statement, all variables and given/known data
    The path of a very small satellite S in an elliptical orbit around a massive spherical planet P is shown in the figure. The distance from 3 to 4 is the same as from 4 to 5, 9 to 10, and 10 to 11.
    (Select T-True, F-False, G-Greater than, L-Less than, E-Equal to, If the first is T and the rest F, enter
    TFFFFFF).

    A) The total PE + KE of S at `4' is .... that at `9'.
    B) The magnitude of the force on S at `2' is .... at `8'.
    C) The PE of S varies with position.
    D) The torqe exerted on S is constant
    E) S has its minimum speed at `10'.
    F) The speed of S at position `2' is .... at `8'.
    G) P could be at position X for the orbit of S shown.


    2. Relevant equations



    3. The attempt at a solution

    A) The total PE + KE of S at `4' is .... that at `9'. GREATER THAN
    B) The magnitude of the force on S at `2' is .... at `8'. LESS THAN
    C) The PE of S varies with position. TRUE, depends on R
    D) The torqe exerted on S is constant NOT SURE, FALSE?
    E) S has its minimum speed at `10'. LESS THAN
    F) The speed of S at position `2' is .... at `8'. LESS THAN
    G) P could be at position X for the orbit of S shown. TRUE

    I doubt too many people here go to the university of michigan. Could you upload the diagram somewhere we don't need to log into?
