Question

On a hot, summer day you put both of your hands on a 420-Kg yellow fire hydrant. This is attached properly to an underground water pipe. With all of your might, you push east on that fire hydrant for exactly 60 minutes. It did NOT move. How much work did you do?​

Answer 1

0

Step-by-step explanation:

W = F * d * cos(θ)

In this case, the d (displacement) is zero since the fire hydrant did not move.

Therefore W = F * 0 * cos(θ) = 0
