A physics question about gravitational potential energy!?

Question

A championship weight lifter did 1.10 x 10 to the power of 4 J of work on a set or barbells weighing 3680 N. How much gravitational potential energy did the barbells have at the maximum height of the lift? Show work please.

Answer 1

it's 1.10 x 10 to the power of 4 J

or 11 kJ

no work, you already have the number.
