The image you have provided contains a parabolic trajectory of a ball kicked by Alif, along with some related questions. Based on the diagram and the provided text, here’s a breakdown of the problem:

The diagram shows the trajectory of a ball, with initial velocity \( v_0 = 10 \, \text{m/s} \) and an angle of \( 30^\circ \) above the horizontal axis. There are several points marked on the trajectory: A, B, and C.

Questions 4-8 relate to calculating various aspects of this projectile motion:

1. **Initial velocity components**:
   - The initial velocity has both horizontal and vertical components. The horizontal component is:
     \[
     v_{0x} = v_0 \cos(30^\circ)
     \]
     The vertical component is:
     \[
     v_{0y} = v_0 \sin(30^\circ)
     \]
     
2. **Velocity at point A**: This would require calculating the velocity at that specific point based on the initial velocity components and the time elapsed.
   
3. **Velocity at time \( t = 0.5 \, \text{seconds} \)**: At this point, we can use kinematic equations to calculate the velocity at this specific time.

4. **Maximum height**: The ball reaches its maximum height when the vertical component of the velocity becomes zero. We can calculate this using:
   \[
   v_y = v_{0y} - g t_{\text{max}} = 0
   \]
   where \( t_{\text{max}} \) is the time to reach maximum height, and \( g = 9.8 \, \text{m/s}^2 \) is the acceleration due to gravity.

5. **Horizontal range**: The horizontal distance covered by the ball can be calculated by finding the total time of flight and then using the horizontal component of velocity.

---

I’ll start solving the problems step by step based on the data provided. Let's calculate the initial velocity components first:

\[
v_{0x} = 10 \cos(30^\circ), \quad v_{0y} = 10 \sin(30^\circ)
\]

Let me calculate that for you.The initial velocity components of the ball are:

- Horizontal component \( v_{0x} = 8.66 \, \text{m/s} \)
- Vertical component \( v_{0y} = 5.00 \, \text{m/s} \)

Next, I’ll calculate the answers for the remaining questions.

1. The velocity at point A (which seems to be at the beginning).
2. The velocity at time \( t = 0.5 \, \text{seconds} \).
3. The maximum height reached by the ball.
4. The total horizontal range (maximum distance).

Should I proceed with these calculations?
