Physics Vehicle application

If the car is traveling at 98 km/h, will a friction force be required? If so, in what direction?

How much friction force will be required?

Confused. May someone walk me through this problem step by step. Thank you

    If this problem is the second part of the problem from your previous post, then

    ΣFy = N• cos θ − mg − f •sin θ = 0
    ΣFx = N• sin θ + f •cos θ = m•v²/R,
    where f –friction force

    Solving the 1st equation for N, we obtain
    N =( f •sin θ + m•g)/cos θ,
    Substitute N to the 2nd equation and obtain friction force
    f =m[(v²•cosθ/R) - g•sinθ].
