Explanation:
I'll assume the incline plane is frictionless, as no information is given.
We're asked to find the total work done on a
The force is given by
F = mgsintheta = (1color(white)(l)"kg")(9.81color(white)(l)"m/s"^2)sin((5pi)/12)
= 9.48 "N"
Now, we use the equation
W = Fs (one-dimensional)
to find the necessary work (
W = (9.48color(white)(l)"N")(3color(white)(l)"m") = color(red)(ul(28.4color(white)(l)"J"
