I'm thinking you'd use either W = F/d or W = 1/2mv^2. Answer by solver91311(24713) (Show Source):
In the first place, ask your Physics questions on a Physics homework help site. This site is for mathematics.
In the second place, , which would imply that an infinite amount of work was done on the wall given that the displacement was zero. In fact, . Either of which will give you the correct answer since both displacement and velocity of the wall are zero.
