Manon is riding her bicycle home from the university. She pedals to the top of a hill with a 28 incline. At the peak, her velocity is 5m/s. She stops pedalling and coasts 110m down the hill. What is her final speed at the bottom of the hill? Assume the kinetic friction coefficient in her bike wheels is 0.15 and the kinetic friction between the tires and the ground is 0.8. Solve this problem using conservation of energy
