6. A horizontal tabletop is divided into two parts that have different surface texture. A thin uniform disk spinning clockwise about its axis is placed on tabletop. The coefficients of sliding friction between them are i1=3/8,i2=1/4 as shown . initially the center of disk is located right over the line dividing the tabletop. The initial acceleration of the C.O.D. is given by g/xpi then x is.

A $1.5$ kg block at rest on a tabletop is attached to a horizontal spring having a spring constant of $19.6$ N/m. The spring is initially unstretched. A constant $20.0$ N horizontal force is applied to the object causing the spring to stretch.Determine the speed of the block after it has moved $0.30$ m from equilibrium if the coefficient of kinetic friction between block and tabletop is $0.20$ .
