1. Let's first state the problem: Solve question 5c using the swing method. 2. The swing method is typically used in physics or engineering to analyze pendulum motion or oscillations. It involves calculating the period or frequency of a swinging object. 3. The formula for the period $T$ of a simple pendulum is given by: $$T = 2\pi \sqrt{\frac{L}{g}}$$ where $L$ is the length of the pendulum and $g$ is the acceleration due to gravity. 4. Important rules: - The pendulum must swing with small amplitude for the formula to be accurate. - The acceleration due to gravity $g$ is approximately 9.8 m/s$^2$ on Earth. 5. To solve question 5c, we need the length $L$ of the pendulum or the parameters given in the problem. 6. Since the user did not provide the exact details of question 5c, please provide the length $L$ or the problem statement for precise calculation. 7. Once $L$ is known, substitute it into the formula and calculate $T$. 8. For example, if $L=1$ meter: $$T = 2\pi \sqrt{\frac{1}{9.8}} = 2\pi \sqrt{0.102} = 2\pi \times 0.319 = 2.006 \text{ seconds}$$ 9. This means the pendulum completes one full swing in approximately 2.006 seconds. 10. If you provide the exact parameters of question 5c, I can help solve it step-by-step using the swing method.
