Questiоn 2 — After the rоpe breаks (10 pоints) An 8.00 kg box stаrts from rest on а level floor. A rope pulls it to the right with a force of 52.0 N at 25.0° above the horizontal. The coefficient of kinetic friction is 0.180. The rope breaks after 1.80 s; the box keeps sliding until it stops. Take right and up as positive. Use g = 9.80 m/s² and kinetic friction while the box is sliding. Show your work: Draw free-body diagrams for the box before and after the rope breaks. Label every force and identify what changes. (2 pts) Calculate the normal force and kinetic friction in both stages. Explain why the two friction forces are different. (2 pts) Write the horizontal force equation for each stage and calculate both signed accelerations. (2 pts) Find the speed at the instant the rope breaks. (1 pt) Calculate the additional distance the box slides after the break. Show your substitutions. (2 pts) Sketch velocity versus time from the start until the box stops. Mark the time of the break and both slopes. Why is there no sudden jump in speed? (1 pt) Upload ONE PDF at the end of the exam containing all of your written solutions.
