A traditional, double-seat chairlift can move1200 people per hour (with an average mass of 60.0 kg) up a ski hill. A high-speed quad chair can move 2400 people in 30.0 minutes up the hill. If the upper terminal is 100 m higher than the lower terminal, how much power would each type of lift need just to overcome the force of gravity? Explain why they would need more power than the amount used to overcome the force of gravity.
I know that the traditional chairlift will be moving 72000kg/hr, and that the high speed quadruple chairlift will be moving 288000kg/hr.
How do I find the amount of upwards force required?
Also, would the lifts need more power than the amount used to overcome the force of gravity due to the fact that the people must be transported horizontally AND vertically?
Any help is greatly appreciated,
