A ski lift has a one?way length of 1,197 m and a vertical rise of 277 m. The chairs are spaced 19 m apart, and each chair can seat three people. The lift is operating at a steady speed of 8 km/h. Neglecting friction and air drag and assuming that the average mass of each loaded chair is 296 kg, determine the power required to operate this ski lift, in kW.
Also estimate the power required to accelerate this ski lift in 6.4 s to its operating speed in kW.
