Aski lift has a one-way length of 1 km and a vertical rise of 200 m. the chairs are spaced 20 m apart, and each chair can seat three people. the lift is operating at a steady speed of 10 km/h. neglecting friction and air drag, and assuming that the average mass of each loaded chair is 250 kg, determine the power required to operate this ski lift. also, estimate the power required to accelerate this ski lift in 16 s to its operating speed when it is first turned on.
power is needed for (1) acceleration and (2) lifting the loaded chairs. this two parts can be calculated separately and then added together.

Click the game tab at the bottom of the simulation and select level 1. (there is no seesaw balance for this part of the activity.) balance the first equation, and click check to see if you got it right. if you can’t balance it in the first try, you can try again. work through the five equations for level 1. click continue to go on to level 2, and later level 3. each level is more difficult than the one before. keep trying until all the equations are balanced. in one or two sentences, describe how you did in the balancing game. in a few more sentences, explain one strategy you learned for balancing more complex equations.
