How much friction force will be required?

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

**Elena**, Sunday, June 17, 2012 at 8:13amIf 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].
