A 1.8 kg block at rest on a table is attached to a spring of
spring constant 1.1 N/m that is parallel to the table top. The
spring is initially unstretched. A constant 27.9 N force is
applied, causing the spring to stretch.
Determine the speed of the block after it has moved 0.2 m from equilibrium if
1. the tabletop is frictionless
2. the coefficient of kinetic friction is 0.24
