Question

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? ​

Answer 1

Answer:

Work done =force*displacement along the direction of force

So work done=140*15=2100 Joules

Answer 2

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:

$\to \sf W=140 \times 15$

$\leadsto \sf{\red{2100J}} \bigstar$

∴Work done is 2100 J.
