Please use the formulas in the second picture. 

Please write known and unknown like y = ?, x = ?, etc. too and show work in an easy to understand way.

 

 

**Projectile Motion, Constant Acceleration Formulas**

**X Components (Horizontal):**

- \( v_x = v_{x0} + a_x t \)
- \( x = x_0 + v_{x0} t + \frac{1}{2} a_x t^2 \)
- \( v_x^2 = v_{x0}^2 + 2a_x (x - x_0) \)

**Projectile (Horizontal):**

- \( v_x = v_{x0} \)
- \( x = x_0 + v_{x0} t \)
- \( v_x^2 = v_{x0}^2 \)

---

**Y Components (Vertical):**

- \( v_y = v_{y0} + a_y t \)
- \( y = y_0 + v_{y0} t + \frac{1}{2} a_y t^2 \)
- \( v_y^2 = v_{y0}^2 + 2a_y (y - y_0) \)

**Projectile (Vertical):**

- \( v_y = v_{y0} - gt \)
- \( y = y_0 + v_{y0} t - \frac{1}{2} gt^2 \)
- \( v_y^2 = v_{y0}^2 - 2g (y - y_0) \)

**Problem Statement:**

1. In the given picture, Alice throws the ball to the +X direction with an initial velocity of 10 m/s. The time elapsed during the motion is 5 seconds. Calculate the height from which the object is thrown and the Vy component of the velocity after it hits the ground.

**Diagram Explanation:**

- Alice is standing on the edge of a cliff and throws a ball horizontally.
- The initial velocity of the ball is shown as a horizontal arrow labeled \( V = 10 \, \text{m/s} \).
- The ball's trajectory is depicted as a curved path from the edge of the cliff to the ground.
- A vertical distance marker labeled \( h = ? \) indicates the unknown height of the cliff.
- The point where the ball hits the ground is labeled with \( t = 5s \).
- The vertical component of the velocity at the impact point is labeled \( Vy = ? \).

**Key Concepts:**

- The horizontal motion and vertical motion are independent.
- The initial vertical velocity (\( Vy_0 \)) is 0 m/s since the ball is thrown horizontally.
- Use kinematic equations to solve for \( h \) and \( Vy \).
