How much work is being done?

[bcalkins]

A farmhand pushes a 26-kg bale of hay 3.9 meters across the floor of a barn. If she exerts a horizontal force of 88N on the hay, how much work has she done?

My Answer:
W=88N x 3.9m
= 343.2 Joules

My question: Is this correct or do I have to do something with the mass of 26-kg?
Thank you!

Perfectly correct. The mass is irrelevant. (But maybe the question has another part.)
