Question

How much work would it take to push a `8 kg` weight up a `15 m` plane that is at an incline of `pi / 4`?

Answer 1

Work `W=831.5575747" "`joules

Explanation:

The given data are
mass `m=8" "`kg
angle `theta=pi/4`

distance `d=15" "`meters

Let `F` be the force required to push the object up the plane

the working equation

`F=mg*sin theta`
`F=8*(9.8)*sin (pi/4)`
`F=55.43717165" "`N

Solve for the work `W`

`W=F*d`
`W=55.43717165(15)`
`W=831.5575747" "`Joules

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