A chair lift takes skiers to the top of a mountain that is 320 m high. The average mass of skiers complete with equipment is 85 kg . The chair lift can deliver three skiers to the top of the mountain every 36 s

Determine the power required to carry out this task

If friction increases the power by 25% what power must the motor running the lift be able to deliver

• physics -

massrate= 85/36 kg/second

power= force*distance/time= force/time *distance
= massrate*g*distance

I am not certain what the last question states.
