    Definition of 'with the vertical' in this question?

    Homework Statement (please ignore something that is not english) Homework Equations ac=v^2/r Fc is about 6.0E3 N and ac is about 5.0 m/s^2 (b) is the problem... The Attempt at a Solution what is 'with the vertical' here? the direction/opposite of ac or the direction of v?
