Question

How much work would it take to push a `1 kg` weight up a `4 m` plane that is at an incline of `(5pi) / 12`?

Answer 1

I found: `W=37.86J`

Explanation:

you can use the height `h` of the ramp into the experssion for work:

`W=mgh`

where (from trigonometry):

`h=4sin(5pi/12)=3.86m`

So that:
`W=1*9.8*3.86=37.86J`
