The coefficient of friction between the 2-lb block and the surface is = 0.2. The block is acted upon by a horizontal force of P. Determine the maximum deformation of the outer spring B at the instant the block comes to rest. Spring B has a stiffness of KB = 20 lb/ft and the "nested" spring C has a stiffness of kc = 40 lb/ft.
[A].
xB = 1.154 ft
[B].
xB = 0.790 ft
[C].
xB = 0.923 ft
[D].
xB = 1.137 ft
