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

The work is `10.36 J`

Explanation:

The work can be calculated as:

`W=F*S*cos alpha`

The force `F` is:

`F=m*g`

So:

`W=m*g*s*cos alpha`

`W=1*10*4*cos((5pi)/12)`

`W=1*10*4*0.259=10.36`
