Solving a problem in physics, section 62, point 38 wave

38. Board with the bar lying on it makes a horizontal harmonic oscillations with an amplitude of A = 15 cm. Determine the coefficient of friction μ between the board and bar when the bar starts to slide over the board when it becomes less than the oscillation period T = 2.0 s.
