Question

A pair of bullocks exerts a force of 1400 N on a plough . The field being ploughed is 15 m long . How much work is done in ploughing the length of the field?

Answer 1

$\LARGE{\bf{\underline{\underline{GIVEN:-}}}}$

• Force (F) = 1400 N.
• Distance (s) = 15m.

$\LARGE{\bf{\underline{\underline{TO \ FIND:-}}}}$

• The work done (w)

$\LARGE{\bf{\underline{\underline{SOLUTION:-}}}}$

We can use the formula for work done:

$\mapsto \sf{\green{W=Fs}}$

Where:

• F is force.
• s is distance.

Substituting the values, we get:

$\to \sf W=1400 \times 15$

$\leadsto \sf{\red{21000J}} \bigstar$

∴Work done is 21000 J.
