A m = 2.51 kg mass starts from rest and slides a distance d down a frictionless theta = 34.6° incline. While sliding, it comes into contact with an unstressed spring of negligible mass.

The mass slides an additional 0.220 m as it is brought momentarily to rest by compression of the spring (k=440 N/m). Calculate the initial separation d between the mass and the spring.
