Sample Questions and Memorandum Approaches

Example 1: Physics - Force and Motion

Question: A car accelerates from 0 to 20 m/s in 10 seconds. Calculate the acceleration and the distance traveled during this time.

Memorandum Approach:

1. Identify knowns:

• Initial velocity, u = 0 m/s
• Final velocity, v = 20 m/s
• Time, t = 10 s

2. Calculate acceleration (a):

\[

a = \frac{v - u}{t} = \frac{20 - 0}{10} = 2\, \text{m/s}^2

\]

3. Calculate distance (s):

\[

s = ut + \frac{1}{2}at^2 = 0 + \frac{1}{2} \times 2 \times (10)^2 = 1 \times 100 = 100\, \text{m}

\]

4. Answer:

• Acceleration = 2 m/s²
• Distance traveled = 100 meters

Key Point: Show all steps clearly, label answers appropriately, and include units.

Example 2: Chemistry - Balancing Equations

Question: Balance the following chemical equation:

\[ \text{C}_2\text{H}_6 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \]

Memorandum Approach:

1. Write unbalanced equation:

\[

\text{C}_2\text{H}_6 + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O}

\]

2. Balance carbon atoms:

• 2 carbons on the left, so:

\[

\text{C}_2\text{H}_6 + \text{O}_2 \rightarrow 2\, \text{CO}_2 + \text{H}_2\text{O}

\]

3. Balance hydrogen atoms:

• 6 hydrogens on the left, so:

\[

\text{C}_2\text{H}_6 + \text{O}_2 \rightarrow 2\, \text{CO}_2 + 3\, \text{H}_2\text{O}

\]

4. Balance oxygen atoms:

• On the right: (2×2) + (3×1) = 4 + 3 = 7 oxygen atoms
• On the left: O₂ molecules, so:

\[

\text{O}_2 \rightarrow \text{O}_2 \text{ molecules}

\]

To get 7 oxygen atoms, use 7/2 O₂ molecules:

\[

\text{C}_2\text{H}_6 + \frac{7}{2} \text{O}_2 \rightarrow 2\, \text{CO}_2 + 3\, \text{H}_2\text{O}

\]

5. Eliminate fraction (multiply entire equation by 2):

\[

2\, \text{C}_2\text{H}_6 + 7\, \text{O}_2 \rightarrow 4\, \text{CO}_2 + 6\, \text{H}_2\text{O}

\]

6. Final balanced equation:

\[

\boxed{2\, \text{C}_2\text{H}_6 + 7\, \text{O}_2 \rightarrow 4\, \text{CO}_2 + 6\, \text{H}_2\text{O}}

\]

Note: Show all steps and reasoning.
