An object of mass m starts from rest and slides a distance d down a frictionless incline of angle. While sliding, it contacts an unstressed spring of negligible mass as shown in Figure. The object slides an additional distance x as it is brought momentarily to rest by compression of the spring (of force constant k). Find the initial separation d between object and spring. (Use theta, g for acceleration due to gravity, and m, k and x as necessary.)

Solution Summary

A block released on an incline compresses the spring and moves up again, the initial separation is calculated.
