14.51.Model:The two blocks are in simple harmonic motion, without the upper block slipping. We will also apply the model of static friction between the two blocks. Visualize:Solve:The net force acting on the upper block 1mis the force of friction due to the lower block 2.mThe model of static friction gives the maximum force of static friction as ()()sss11maxmaxsmaxfnm gm aagμμμ===⇒=Using
