The image you have uploaded contains a physics problem involving projectile motion. Here's the translated problem from the image:

---

A ball is thrown from point \( O \), and 4 seconds later, it lands on the roof of a building at point \( P \), at a height \( h = 20 \) meters above point \( O \). The ball was thrown at an angle \( \theta = 60^\circ \) relative to the horizontal plane. 

The problem asks:

a. Determine the vertical component of the velocity when the ball hits the roof.

b. Determine the horizontal distance \( d \) covered by the ball before hitting the roof.

c. If the thrower moves towards the building until the distance to the wall of the building is 20 m, and the ball is thrown at an initial angle of \( 30^\circ \) with an initial speed of 40 m/s, at what height will the ball hit the wall?

Would you like me to go step by step through the solutions, or address specific parts of the problem?

Here are 5 related questions:

1. How do we calculate the horizontal and vertical components of velocity in projectile motion?
2. What are the equations of motion used for calculating the horizontal distance of a projectile?
3. How does changing the angle of projection affect the range of a projectile?
4. What role does time of flight play in determining the final velocity of a projectile?
5. How do we account for gravity when calculating the motion of a projectile?

**Tip:** Remember that the horizontal and vertical motions of a projectile are independent of each other, but they share the same time of flight.

A ball is thrown from point O, and 4 seconds later, it lands on the roof of a building at point P, at a height h = 20 meters above point O. The ball was thrown at an angle θ = 60° relative to the horizontal plane. The problem asks for: a. Vertical component of velocity when the ball hits the roof, b. Horizontal distance d covered by the ball, c. The height at which the ball will hit the wall if the thrower moves closer to the building and the ball is thrown at a different angle and speed.
