1. The 25-kg box is launched from the position shown along the rough horizontal plane with the velocity of 8 m/s. Determine the distance x that the box will travel before the spring stops forward motion. The coefficient of kinetic friction between the box and the plane is 0.2 and the spring constant is 150 N/m.
