  1. μ = 0.7
    N = mg
    g = 9.8 m/s^2
    m = 2000 kg
    a = angular acceleration = v^2/r

    F = μN = ma =mv^2/r
    v = sqrt(μNr/m) = sqrt(μgr) = 12 m/s

  2. 1)first find the FN
    Fn = m x g

    2)then find the Ff using the Ff = us x Fn

    3) use F = ma formula and isolate a
    a = F/m

    4) finally use a = V^2/r formula

    you will then get 11.719...N
    hope this helped
