Answer:
The work done is 1600 J.
Step-by-step explanation:
Given that,
Distance = 80 m
Force = 20 N
We need to calculate the work done
The work done is equal to the product of the force and displacement.
Using formula of work done

Where, F = force
d = displacement'
Put the value into the formula


Hence, The work done is 1600 J.
