    1. The problem statement, all variables and given/known data

    In the attach

    2. Relevant equations

    Newton Laws

    3. The attempt at a solution

    Ok, I did the first one, came up with T2 = 8.736, is that right?
    What is the net force?
    How do I do the third one?

    10x in advance.

    Shalom asi123! :smile:

    Yes, your T2 is right! :smile:

    The net force is the vector sum of all the forces.

    (By Newton's second law, it will be equal to mass times acceleration.)

    Just add all the forces (obviously, the vertical components cancel, so you only have to add the horizontal components :wink:)

    The use the formula for centripetal acceleration to find the speed. :smile:
