On a hot summer day you put both of your hands on a 420-kg yellow fire hydrant this attached properly to an underground water pipe with all your might you push east on the fire hydrant for 60 minutes it did not move how much work did you do ?
To determine the work done, we need to calculate the force applied and the displacement.
Force = mass * acceleration
Here, the mass of the fire hydrant is given as 420 kg.
The acceleration in this case is zero since the hydrant did not move. Therefore, the force applied is zero.
Work = force * displacement
Since the force applied is zero, the work done is also zero.
In this scenario, you did not do any work on the fire hydrant.
