Explanation:
W=14700Nm
<u>Explanation:</u>
Work done is calculated by multiplying external force acting on the object by the amount of movement of an object.
Here an External Force of 700 N is acting or applied on an object which moves the objects to 21 m from its initial position.
the formula for work done is W=F*d
where F is External Force acting on the object.
and d is the amount of distance moved by the object.
W=700*21
W=14700 Nm
