A pair of bullocks exerts a force of 140 N on a plough. The field being ploughed is 15 m long. How much work is done in ploughing the length of the field?
Given:
Force (F) = 140N
Displacement (s) = 15m
Work done = Force × displacement
W = F × s
W =140N × 15m
= 2100Nm
W = 2100 J
Therefore the work done = 2100J.
