┌─────────────────────────────────────────────────────────────┐ │ Chapter 5 – Friction M. Karim Prob 5.9 │ ├─────────────────────────────────────────────────────────────┤ │ Problem: A block of mass 5 kg rests on a rough horizontal │ │ surface (μ = 0.4). A horizontal force of 18 N is applied. │ │ Find friction force and acceleration. (g = 10 m/s²) │ ├─────────────────────────────────────────────────────────────┤ │ DATA: m = 5 kg, μ = 0.4, F_app = 18 N, g = 10 m/s² │ │ │ │ STEP 1: Max static friction │ │ f_max = μ × m × g = 0.4 × 5 × 10 = 20 N │ │ │ │ STEP 2: Compare applied force │ │ F_app (18 N) < f_max (20 N) → block does NOT move. │ │ │ │ STEP 3: Actual friction = applied force (static eq.) │ │ ∴ f = 18 N and a = 0 m/s² │ │ │ │ ✔️ Common Error: Students wrongly take f = μ×N = 20 N │ │ even when block is stationary. │ │ │ │ ANSWER: Friction = 18 N, Acceleration = 0 │ └─────────────────────────────────────────────────────────────┘ m karim physics numerical book solution class 11
