A cyclist is coasting at \(12 \mathrm{~m} / \mathrm{s}\) when she starts down a \(450-\mathrm{m}\)-long slope that is \(30 \mathrm{~m}\) high. The cyclist and her bicycle have a combined mass of \(70 \mathrm{~kg}\). A steady \(12 \mathrm{~N}\) drag force due to air resistance acts on her as she coasts all the way to the bottom. What is her speed at the bottom of the slope?
