Answer:
w = 400 joules
Step-by-step explanation:
Work done is the force that causes the displacement of an object. Work done is the product of force and distance. A force acting on an object is only regarded as a work done if the object has an appreciable displacement.
Mathematically,
Work = force × distance
force = 40 Newton
distance = 10 m
W = 40 × 10
w = 400 joules
