Answer to Question #83382 in Mechanics | Relativity for Paolo

Question

A 1.00 kg object slides to the right on a surface with kinetic friction coefficient of 0.25. The initial speed of the object when it makes contact with a light spring
(kspring =50.00 N/m) is 3.00 m/s. The object comes to rest after the spring has been compressed a distance d. The object is then forced toward the left by the spring and continues to move in that direction beyond the spring’s un-stretched position. Finally, the object comes to rest a distance D to the left of the un-stretched spring.
Find d, D , and the speed v at the un-stretched position when the object is moving to the left.
