Question

### Projectile Motion and Velocity

**Projectile Motion Example:**

"A boy tosses a ball into the air so it follows the 2-D parabolic curve in x and y as shown in the drawing."

**Problem Statement:**

Using this figure, identify at which of the points the ball's velocity is zero.

**Diagram Explanation:**

- **Axes and Notation:**
- The diagram shows a 2-dimensional coordinate system with the x-axis (horizontal) and y-axis (vertical).
- The ball follows a parabolic trajectory.
- The initial velocity vector of the ball is denoted as \( V_0 \).

- **Trajectory Points:**
- The trajectory includes four key points labeled A, B, C, and D.
- Point A is near the beginning of the parabola.
- Point B is at the peak of the parabola.
- Point C is descending on the parabola.
- Point D is at the end of the parabola, just before the ball lands.

**Important Concept:**

- At the peak of the projectile's path (Point B), the vertical component of the ball's velocity is zero. This does not mean the overall velocity is zero, only that the upward or downward motion is momentarily at rest as the direction changes.

Understanding this concept is crucial in the study of projectile motion, which is a common topic in physics education.

A baseball is hit at an angle 0 and travels along a parabolic arc before it strikes the ground. Which one of the following statements is true? O The acceleration of the ball decreases as the ball moves upward. O The velocity of the ball is O when the ball is at the highest point in the arc. O The acceleration of the ball is 0 when the ball is at the highest point in the arc. O The velocity of the ball is a maximum when the ball is at the highest point in the arc. O None of the above.

A boy decides to propose to his girlfriend in a hot air balloon. They are in the balloon, and it is moving 15 degrees south of east at a velocity 10 m/s relative to the air. When the balloon has a height of 90 m the boy is about to propose to but he drops the ring. The wind is also blowing to the east at 12 m/s relative to the ground. They now need to find the ring. a) What is the horizontal distance ( magnitude and direction) the ring lands on the ground from where it drops out of the balloon? b) What is the final velocity of the ring right before it hits the ground? c) Draw the vertical position vs time graph, velocity vs time graph, and acceleration vs time graph of the ring.
