KE = mgh, so the kinetic energy just before impact is proportional to drop height. For m = 10 kg:
- h = 1 m → KE = 10·9.8·1 ≈ 98 J
- h = 2 m → KE ≈ 196 J
- h = 3 m → KE ≈ 294 J
Pick the graph that shows KE increasing in the ratio 1:2:3 (largest at 3 m, middle at 2 m, smallest at 1 m) — i.e. a straight-line increase with height.
