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?
