Part 3: Mathematical Setup
📐 Free Body Diagram Construction:
1. Gravitational force: F_g = mg = 5 × 9.8 = 49N (downward)
2. Normal force: N (perpendicular to surface)
3. Friction force: f = μN (up the plane, opposing motion)
Part 4: Coordinate System Choice
🎯 Optimal Coordinate System:

Part 5: Force Resolution
📊 Component Analysis:
- Weight components:
* Parallel to incline: F_g∥ = mg sin30° = 49 × 0.5 = 24.5N
* Perpendicular to incline: F_g⊥ = mg cos30° = 49 × 0.866 = 42.4N
Part 6: Applying Newton's Second Law
⚗️ Force Balance Equations:
y-direction (perpendicular to incline):
ΣF_y = N - F_g⊥ = 0 (no acceleration perpendicular to surface)
N = F_g⊥ = 42.4N
x-direction (parallel to incline):
ΣF_x = F_g∥ - f = ma
Where f = μN = 0.2 × 42.4 = 8.48N
Part 7: Solution Calculation
🔢 Final Calculation:
ma = F_g∥ - f = 24.5 - 8.48 = 16.02N
a = 16.02/5 = 3.20 m/s²

Comprehensive Solution Framework:
Part 1: Theoretical Foundation
📚 Energy Conservation Principles:

Part 4: Initial Energy Calculation
⚗️ Initial State Analysis:
Height above reference: h = L(1 - cosθ) = 2(1 - cos60°) = 2(1 - 0.5) = 1m
Initial energy: E_i = PE_i + KE_i = mgh + 0 = 0.5 × 9.8 × 1 = 4.9J
Part 5: Final Energy Calculation
🔢 Final State Analysis:
Height: h_f = 0 (at reference level)
Final energy: E_f = PE_f + KE_f = 0 + ½mv²
Part 6: Energy Conservation Application
⚡ Equating Energies:
E_i = E_f → 4.9 = ½mv²
4.9 = ½ × 0.5 × v²
4.9 = 0.25v²
v² = 4.9/0.25 = 19.6
v = √19.6 = 4.43 m/s

- Stoichiometry: 2 moles Al react with 1 mole Fe₂O₃
Part 2: Molar Calculations
🔍 Quantitative Analysis:
Aluminum (Al):
- Atomic mass: 27 g/mol
- Moles available: 54g/27g/mol = 2.0 mol
Iron(III) oxide (Fe₂O₃):
- Molar mass: (2×56) + (3×16) = 112 + 48 = 160 g/mol
- Moles available: 160g/160g/mol = 1.0 mol
Part 3: Stoichiometric Requirements
📐 Reaction Requirements Analysis:
From balanced equation: 2Al + Fe₂O₃ → products
Required ratio: n(Fe₂O₃)/n(Al) = 1/2 = 0.5
Available ratio: n(Fe₂O₃)/n(Al) = 1.0/2.0 = 0.5
Part 4: Limiting Reactant Identification
⚗️ Detailed Analysis:
Since available ratio (0.5) = required ratio (0.5), neither reactant is limiting
Both reactants will be completely consumed in the exact stoichiometric ratio
Part 5: Product Calculation
🔢 Product Quantities:
Aluminum oxide (Al₂O₃):
- From equation: 2Al → 1Al₂O₃
- Moles produced: 2.0 mol Al × (1 mol Al₂O₃/2 mol Al) = 1.0 mol
- Mass: 1.0 mol × (2×27 + 3×16) g/mol = 1.0 × 102 g = 102g
Iron (Fe):
- From equation: 2Al → 2Fe
- Moles produced: 2.0 mol Al × (2 mol Fe/2 mol Al) = 2.0 mol
- Mass: 2.0 mol × 56 g/mol = 112g

Integration by Parts - Deep Analysis:
Problem: "Evaluate ∫x ln(x) dx"
Comprehensive Solution Framework:
Part 1: Theoretical Foundation
📚 Integration by Parts Theory:
- Formula: ∫u dv = uv - ∫v du
- Derivation from product rule: d(uv) = u dv + v du
- Strategic choice of u and dv based on LIATE rule
Part 2: Strategy Selection
🎯 Method Analysis:
Why integration by parts?
- Product of algebraic and logarithmic functions
- Direct substitution not applicable
- Standard integration formulas don't apply
Part 3: Function Analysis
📊 Function Characteristics:
- Domain: x > 0 (ln(x) defined only for positive x)
- Behavior: ln(x) grows slowly, x grows linearly
- Product behavior: x ln(x) grows as x ln(x)
Part 4: Integration by Parts Setup
🔢 Variable Selection:
Choose: u = ln(x) and dv = x dx
Reasoning:
- u = ln(x): du = (1/x) dx (simpler)
- dv = x dx: v = x²/2 (integrable)
- Alternative choice would complicate rather than simplify
Part 5: Step-by-Step Solution
⚗️ Detailed Calculation:
Step 1: Apply formula
∫x ln(x) dx = uv - ∫v du
Step 2: Calculate components
u = ln(x), du = (1/x) dx
dv = x dx, v = x²/2
Step 3: Substitute
∫x ln(x) dx = ln(x) × (x²/2) - ∫(x²/2) × (1/x) dx
= (x²/2) ln(x) - ∫(x/2) dx
= (x²/2) ln(x) - (1/2) ∫x dx
Step 4: Complete integration
= (x²/2) ln(x) - (1/2) × (x²/2) + C
= (x²/2) ln(x) - x²/4 + C
Step 5: Factor common terms
= x²/4 [2 ln(x) - 1] + C
Part 6: Verification
✅ Differentiation Check:
d/dx [x²/2 ln(x) - x²/4 + C]
= x ln(x) + x²/2 × (1/x) - x/2
= x ln(x) + x/2 - x/2
= x ln(x) ✓
