The coefficient of friction between the 2-lb block and the surface is μ=0.2. the block has an initial speed of vβ =6 ft/s and is acted upon by a horizontal force of p=15 lb. 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.
