A ski lift has a one-way length of 1495m and a vertical rise of 285 m. The chairs are spaced 23 m apart, and each chair can seat three people. The lift is operating at a steady speed of 12 km/h. Neglecting friction and air drag and assuming that the average mass of each loaded chair is 282kg, determines the power required to operate this ski lift. Also estimate the power required to accelerate this ski lift in 4.7 s to its operating speed when it is first turned on
