Question

How much work would it take to push a `9 kg` weight up a `11 m` plane that is at an incline of `pi / 12`?

Answer 1

Work`=251.1062376" "`joules

Explanation:

The given data:

`theta=pi/12=15^@`
mass `m=9" "`kg
distance `d=11" "`m

Let `F` be the required force to push the weight
Let `W` be the work in joules

`F=m*g*sin theta`

`F=(9)(9.8)sin 15^@`

`F=22.82783978" "`N

Compute work `W`

`W=F*d=22.82783978(11)`

`W=251.1062376" "`Joules

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