Answer #1

Constant speed means no acceleration, that means net force must be zero.

net force = applied force - resistive force

net force is zero and resistive force is given zero therefore applied force will be zero.

Work = force x displacement

Since force is zero therefore work will be zero.

Answer is 0 J

That is option a.
