Unformatted text preview: 65. (a) Using F = μ s mg , the coefficient of static friction for the surface between the two blocks is μ s = (12 N)/(39.2 N) = 0.31, where mt g = (4.0 kg)(9.8 m/s2)=39.2 N is the weight of the top block. Let M = mt + mb = 9.0 kg be the total system mass, then the maximum horizontal force has a magnitude Ma = Mμs g = 27 N. (b) The acceleration (in the maximal case) is a = μsg =3.0 m/s2. ...
