Question

How much work would it take to push a `2 kg` weight up a `18 m` plane that is at an incline of `(5pi) / 12`?

Answer 1

Work `W=340.7786315" "`joules

Explanation:

We compute the force F needed to push the weight

`F=mg sin ((5pi)/12)=2(9.8)sin ((5pi)/12)=18.9321462" "`N

The work `W`

`W=F*d=18.9321462*18=340.7786315" "`joules

God bless....I hope the explanation is useful.
