distance of 62.3 m, the longest escalator in

the free world.

The acceleration of gravity is 9.8 m/s^2 :

How much work did the escalator do on

Karen if it has an inclination of 34 degrees? Answer

in units of J.

2. Relevant equations

3. The attempt at a solution i got the height to equal 34.83771789. i dunno if that helps or is needed.
