The work done is given by the formula:
work = force x distance x cos(theta)
where theta is the angle between the force and the direction of motion. Since the force is applied in the same direction as the motion, theta = 0 and cos(theta) = 1.
Substituting the given values, we get:
work = 100 N x 2 m x 1
work = 200 J
Therefore, the answer is C. 200 J.
