Answer:
1007.94 J
Step-by-step 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
