A cyclist is coasting at 14 m/s when she starts down a 440 m long slope that is 30 m high. The cyclist and her bicycle have a combined mass of 70 kg. A steady 13 N drag force due to air resistance acts on her as she coasts all the way to the bottom. Required:
What is her speed at the bottom of the slope?
