(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

what is the minimum wirk neede to push a 1000kg car 300m up a 17.5^{o}incline?

Part a. Ignore friction

2. Relevant equations

So we are allowed to use the general equation

W=FdCos [tex]\theta[/tex]

3. 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 x10^{5}Joules

Does anyone know what I am doing wrong?
