Question

A 1.00-kg object slides to the right on a surface having a coefficient of kinetic friction 0.250. The object has a speed of vi = 3.00 m/s when it makes contact with a light spring that has a force constant of 50.0 N/m. The object comes to rest after the spring has been compressed a distance . The object is then forced toward the left by the spring and continues to move in that direction beyond the spring’s unstretched position. Finally the object comes to rest a distance D to the left of the unstretched spring.

Find:

a- the distance of compression d.

b- the speed v at the unstretched position when the object is moving to the left.

c- the distance D where the object comes to rest.
