A 8 kg mass slides to the right on a surface
having a coefficient of friction 0.24 as shown.
The mass has a speed of 5 m/s when contact is
made with a spring that has a spring constant
166 N/m. The mass comes to rest after the
spring has been compressed a distance d. The
mass is then forced toward the left by the
spring and continues to move in that direction
beyond the unstretched position. Finally the
mass comes to rest a distance D to the left of
the unstretched spring.
