Desperately need help with a physics problem!

[chicken]

sorry I didn't post it in the official homework thread. I need to figure this out ASAP!

massive karma for anyone who can help. The field is conservative and I can do part b if I know U. the only way I can think to get U would involve WAY more algebra than I think is necessary!

god i feel like i could do this, but i have no background on this physics subject

it's just basic vector calculus. I need to find a scalar function that has this gradient vector field.

problem is. I forgot how to do this!
