**Title: Matching Kinematic Equations with Their Integrated Forms**

**Question 16:** Match the following basic kinematic equations to their respective integrated form at constant acceleration:

1. **\( v = v_0 + a_c t \)**  
2. **\( v^2 = v_0^2 + 2a_c (s - s_0) \)**  
3. **\( s = s_0 + v_0 t + \frac{1}{2} a_c t^2 \)**  

**Integrated Forms:**

1. **\( v = \frac{ds}{dt} \)**  
2. **\( a = \frac{dv}{dt} \)**  
3. **\( a\, ds = v\, dv \)**  

### Explanation of Diagrams:

- **Equation 1:** Represents the relationship between velocity (\(v\)), initial velocity (\(v_0\)), acceleration (\(a_c\)), and time (\(t\)). It's a linear relation describing how velocity changes over time.

- **Equation 2:** Relates the square of velocity to initial velocity squared, acceleration, and the change in position (\(s\)). It is derived from the work-energy principle and links kinetic energy with distance.

- **Equation 3:** Describes position (\(s\)) over time with constant acceleration. It integrates initial position, initial velocity, and acceleration, providing a quadratic relationship between position and time.

**Q24.** The buoyancy force on the 580-kg balloon is \( F = 6 \, \text{kN} \), and the air force acting on the balloon is \( \mathbf{F}_{\text{air}} = \left\{ C_1 \cdot t \, \mathbf{i} - C_2 \cdot \sqrt{t} \, \mathbf{j} \right\} \, \text{N} \), when \( t \) is time in seconds, constants \( C_1 = 24 \) and \( C_2 = 240 \). If the balloon starts from rest, determine its speed after 28 seconds. Neglect the size of the balloon but don’t neglect its weight. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper SI unit. Take \( g = 9.81 \, \text{m/s}^2 \).

**Diagram Explanation:**

The diagram shows a hot air balloon with colored stripes. It includes the following labels:

- An upward arrow labeled \( F = 6 \, \text{kN} \) indicating the buoyancy force.
- A leftward arrow labeled \( \mathbf{F}_{\text{air}} \) indicating the air force.
- Coordinate axes labeled \( x \) and \( y \).

**Your Answer:**
