an object is at rest in front of a compressed spring. it travels over a surface that exerts a kinetic frictional force on it and the object eventually comes to a stop. if the spring constant of the spring is 1800 n/m, the initial compression of the spring is 10 cm, the mass of the object is 2 kg, and the coefficient of kinetic friction between the object and the surface is 0.35, how far does the object travel before it comes to a stop?
