Question 812288: Hi, I could really use your help on this problem here:
A 75 kg man pushes on a 500,000 ton wall for 250 seconds but it doesn't move. How much work does he do on the wall?
I'm thinking you'd use either W = F/d or W = 1/2mv^2.

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.
