Question

How much work would it take to push a `6 kg` weight up a `2 m` plane that is at an incline of `pi / 4`?

Answer 1

`"Work="E_p=82,99 J`

Explanation:

`"given data"`
`m:6 kg`
`l=2m`
`alpha=pi/4`

`h=l.sin pi/4=2*sqrt2/2`

`h=sqrt2=1,41 m`

`"Work="E_p=m*g*h`

`"Work="E_p=6*9,81*1,41`

`"Work="E_p=82,99 J`
