Piano Friction Problem

  1. Sep 2, 2010 #1
    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.

    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.)
