Calculating Coefficient of Friction for Moving a Piano

[xyril1325]

can anyone show me the solution in this problem:

A 1,000-N piano is moved 20 meters across a floor by a horizontal force of 350 N. Find the coefficient of friction.

You show us how you tried to solve the problem. Then you'll get plenty of help.

first, i just divide them, 350/1000=coefficient of friction coz the formula was Ff=(mu)Nf

That's all there is to it. (Assuming that the 350 N force moves the piano at a constant speed.)
