Max speed of cart .

    max speed of cart.....

    A persone rides in a cart moving at a speed v at the top of a hill that is in the shape of an arc of a circle with radius r.
    determine the maximum speed that the cart may travel at the top of the hill without losing contact with the surface.

    How do i know that the cart leaves the surface at values of v.
    what i mean, i dont know the steps or process on solving this. Im trying to think about this logically and im getting no where..

    Some problems can be solved just by looking at them and using some logic. This isn't one of them. You need to create your free body diagram, choose a coordinate system (cylindrical would seem appropriate), write the equations of motion, and go from there.

    You'd be surprised how many physics problems can be solved by just plug-n-chug write the equations of motion and see what you get.
