Consider the mass-on-a-spring system as shown in the gure below. The spring has a spring constant of 1.55e+3 N/m, and the block has a mass of 1.25 kg. There is a constant force of kinetic friction between the mass and the oor of 4.11 N. Starting with the spring compressed by 0.190 m from its equilibrium position, how far will the block travel once it leaves the spring? (Assume that block leaves the spring at at the spring's equilibrium position, marked x=O in the gure. Give your answer as the distance from the equilibrium position to the nal position of the block.)

The pulling force has a magnitude of 13.2 N and is directed at an angle 21.3 degrees above horizontal. If the box is dragged a distance of 12.5 m, what is the magnitude of total energy lost to friction? (Report your answer as a positive number, and be sure to account for the upward component of the pulling force.) Image size: s M L Max m Please enter a numerical answer below.
