Homework Equations
So we are allowed to use the general equation
W=FdCos [tex]\theta[/tex]
The Attempt at a Solution
So I thought you would just do:
W= (1000)(9.8)(300)(cos17.5)
W=2803927Joules
However according to my teacher we should be getting
W= 8.8 x105 Joules
Does anyone know what I am doing wrong?
