If the wall doesn't move, its mean that the work he did is 0 J.
Hello my friend ! Here, I will help you. Alright, before it, I will to introduce to you about work (physics). In the world of physics, work is the amount of force exerted to cause an object to move a certain distance from its starting point. The amount of work will be proportional to the increase in force and increase in displacement. Amount of work can be calculated by this equation :
[tex] \boxed{\sf{\bold{W = F \times s}}} [/tex]
With the following condition :
How about a stationary object like a wall pushed by Mr. Avalos ? Yes it is 0 J. Let's prove it!
Give :
Asked : W = work = ... J
Proven :
[tex] \sf{W = F \times s} [/tex]
[tex] \sf{W = 150 \times 0} [/tex]
[tex] \boxed{\sf{W = 0 \: J}} [/tex] (Q.E.D)
