This is just to see if I am totally confused or making sense.(adsbygoogle = window.adsbygoogle || []).push({});

1. The problem statement, all variables and given/known data

A truck is pushing up a hill on a 30 degree incline. It has a mass of 45 tons. Find the force vector for the truck.

2. Relevant equations

[tex]\vec{F}[/tex] = ||F|| cos[tex]\theta[/tex] i + ||F|| sin[tex]\theta[/tex] j

3. The attempt at a solution

[tex]\vec{F}[/tex] = 45 cos30 i + 45 sin30 j

This is the answer that I assume was wanted, but I don't think that I can say what the force is given only the mass of the truck. After I asked my physics teacher (not the one who gave the quiz), he told me that this is the answer when moving at aconstant velocity. If it was stated in the problem that the truck moved at a constant velocity is this correct?
