Centripetal Force

  1. Mar 9, 2008 #1
    1. An amusement park ride consists of a large vertical cylinder of radius R that spins about its acis fast enough that any person inside is held up against the wall when the floor drops away, as long as the minimum rotational speed is v has been reached. The coefficient of static friction between the person and wall is mew. The period of revolution that produces vmin is T.

    Find T in terms of R mew and g.

    2.An object with mass M is whirled with constant speed v on the end of a string in a horizontal circle of radius R. The string makes angle theta with the horizontal. The tension in the string is T.

    Find the tension in terms of any of the given variables and g.




    a= V^2/r


    I'm stumped. I attempted the the first problem, but couldn't find a relevant equation with T in which to work.
