A 0.77 kg mass, attached to the end of a 0.86 m string, is whirled around in a circular horizontal path. If the maximum tension that the string can withstand is 683 N, then what maximum speed can the mass have if the string is not to break?

  • Physics - ,

    F = m v^2/r

    683 = .77 v^2/.86
    solve for v
