Force - Determining F from U

  • Thread starter Stryder_SW
  • Start date
1. The problem statement, all variables and given/known data

If U = 7x^2 + 9xy + 3(y^2)z, what are the components of the force vector F ?


3. The attempt at a solution
These are the answers I've come up with. I've gotten Fy and Fz correct, but the Fx is wrong and I'm pretty sure its actually right. However, I would love to be proven wrong lol.
Fx=-14x-9y
Fy=-9x-6yz
Fz=-3y^2

Hi Stryder_SW! Welcome to PF! :wink:

Fy=-9x-6yz
Fz=-3y^2
Well, your Fx looks right to me. :smile:
 
yeah, I'm about to message my professor lol.
