Question

How much work would it take to push a `6 kg` weight up a `7 m` plane that is at an incline of `pi / 4`?

Answer 1

`W=291.36J`

Explanation:

`h=7*sin (pi/4)=7*0.707=4.95m" height of object from earth"`

`"work doing is equal to object's potential energy"`

`W=E_p=m*g*h`
`W=6*9.81*4.95`

`W=291.36J`
