The maximum range is $R_{max} = \frac{u^2}{g}$.

• Area covered is a circle: $A = \pi R_{max}^2 = \pi (\frac{u^2}{g})^2 \propto u^4$.
• Ratio: $\frac{A_1}{A_2} = (\frac{u_1}{u_2})^4 = (\frac{1}{2})^4 = 1:16$.

Option D (24.85%) is correct.

ROCE = Profit from operations ÷ Capital Employed × 100

Capital Employed = Shareholders' equity + Non-current liabilities = $423,000 + $80,000 = $503,000

(Current liabilities are excluded from capital employed.)

ROCE = $125,000 ÷ $503,000 × 100 = 24.85%

The textbook identifies three core functional areas that any publication must manage effectively:

1. Editorial: The most important department, responsible for all content — news gathering (field staff/reporters assigned to beats), writing, editing, opinion pieces, and overall editorial policy. Headed by an editor who is ultimately responsible for all published content.
2. Business: Manages financial operations including the advertising department (generating revenue through classified and display ads), circulation department (maximising readership), and accounts department (salaries, procurement, audit reports).
3. Technical/Press: Manages the printing machinery, ensures the newspaper is printed and ready for distribution by deadline, handles newsprint procurement, plate-making, inking, and all mechanical aspects of production.

Effective media management requires managers who understand all three areas, as a failure in any one of them can compromise the entire publication.
