Final answer:
The work done on a box pushed 60 m by a mover exerting a force of 40 N is calculated as the product of force and distance, which equals 2400 J.
Step-by-step explanation:
The amount of work done on an object can be calculated using the formula Work (W) = force (F) × distance (d). In the scenario where a box is pushed 60 m by a mover exerting a force of 40 N, we can multiply the force by the distance to find the work done.
W = F × d = 40 N × 60 m = 2400 J
Therefore, the correct answer is (a) 2400 J.
