in joules, kilojoules, calories, volts, watts, stress... what? In joules it would be... wait! how many newtons does it take to move it?

Work done = force x distance moved in the direction of the force
Force = mass x acceleration
Since the block is moving a constant speed, there is no accelration. Therefore there is no force acting on object. Hence the ork done in moving the object is 0.

hm, an interesting one
w=fa, f=ma
no acceleration so f is 0 so work is 0
