6 pts our rubric

The real Physics 1 Section II is 4 free-response questions in 95 minutes, 50% of your score. Four questions — mathematical routines, translation between representations, experimental design and analysis, and qualitative/quantitative translation. Point totals vary by form; the 2025 exam ran 10 / 12 / 10 / 8 for 40 raw points. This prompt is ours, written to the same skills — score it against the rubric below, not against that structure.

Prompt

A 2.0 kg block is released from rest at the top of a frictionless incline of height 1.8 m. At the bottom it slides onto a horizontal surface with μk = 0.25 and stops.

aUsing energy conservation, find the speed at the bottom of the incline.2 pts

bFind the distance it travels on the rough surface before stopping.2 pts

cOn a labeled axis, sketch kinetic energy vs horizontal distance on the rough surface. (Use g = 10 m/s².)2 pts
