Calculating Normal Force for Blacksmith's Anvil - Newton's Third Law

[rmalski]

Homework Statement

[/B]Find the normal force exerted on a 68.2 kg blacksmith's anvil by the level block of wood that is supporting it.

Homework Equations

[/B]f=ma Ff=uFn

The Attempt at a Solution

[/B]I have tried to find all the forces acting on the anvil while using its mass but I am not correct for some reason. I did 9.8x68.2 and that is all i know what to do right now

Do you have a significant figures issue?

That appears to be the right approach.

Did they say to assume g = 10 m/s/s rather than 9.8 m/s/s?

Did they say to assume up or down is positive?
