Physics:
Using a mass of 1980 kg for a large limestone block (being used to
create a pyramid), how many people does it take to pull this block at
a constant velocity?

Hi there,

It seems that there is some information missing from your
question...are there any other assumptions that you are allowed to
make?

In order to answer this, it is necessary to know the way in which it
is being pulled.

If it is being pulled on a cart, then it depends on the construction
of the cart.

If it is being pulled on a flat surface, then the surface area of the
limestone impinging on the flat surface and the static and kinetic
coefficients of friction between the limestone and that surface.

(And of course the strength of the people).

Actually even with all this information I am not sure I could answer
it, since it would involve having the people pull as slowly as
possible, and here the relationship between the static and kinetic
coefficients gets a little complex at such slow speeds.
