Answer:

1007.94 J

Explanation:

Work done: This can be defined as the product of force and distance, along the direction of the force. The S.I unit of work is Joules (J) .

Form the question above,

W = F×d........................... Equation 1

Where W = Work done, F = Resistive force, d = distance.

Given: F = 21.4 N, d = 47.1 m

Substitute these values into equation 1

W = 21.4(47.1)

W = 1007.94 J
