Question

A 120-meter-long ski ift carries skiers from a station at the foot of a slope to a second station 40 m above. what is the IMA (ideal machincal advantage) of the lift?

Answer 1

The ideal mechanical advantage (IMA) of an inclined plane is given by:

`IMA = (L)/(h)`
where L is the length of the inclined plane while h is the height.
In our problem, L=120 m and h=40 m. Therefore, the IMA of the ski lift is

`IMA= (120 m)/(40 m)=3`
