A \(35\,\text{kg}\) suitcase rests on a luggage-loading ramp inclined \(30.0^\circ\) above the horizontal. A baggage-handler pushes straight into the ramp (perpendicular to the surface) with the minimum force needed to keep it from sliding, \(45\,\text{N}\). Find the coefficient of static friction \(\mu_s\) between the suitcase and the ramp.
