A pair of bullocks exert 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?

Solution

Work done by the bullocks is given by the expression:
Work done = Force x Displacement in the direction of force

Where,
Applied force, $F = 140 N$
Displacement, $s = 15 m$
$W = 140 \times 15 = 2100 J$
Hence, $2100 J$ of work is done in ploughing the length of the field.
