Sample Question Breakdown

Let’s illustrate how to interpret and utilize a typical question from the 2013 memorandum.

Question: Calculate the acceleration of an object sliding down an inclined plane of length 10 meters and height 2 meters, assuming no friction.

Step-by-step approach:

• Identify the knowns:
• Length of incline, \( s = 10\,m \)
• Vertical height, \( h = 2\,m \)
• Gravitational acceleration, \( g = 9.8\,m/s^2 \)

• Determine the acceleration:

Since there’s no friction, the acceleration \( a \) along the incline can be derived from energy considerations or kinematic equations.

• Using the component of gravity:

\[

a = g \sin \theta

\]

where \( \sin \theta = \frac{h}{s} = \frac{2}{10} = 0.2 \)

\[

a = 9.8 \times 0.2 = 1.96\,m/s^2

\]

• Answer according to the memorandum:

The acceleration is 1.96 m/s².

Marking points from the memorandum:

• Correct identification of the right formula.
