In summary, the conversation discusses determining the necessary factors to determine if a ball being kicked in the air will go over a wall of known height. These factors include the initial velocity, the distance to the wall, and determining whether the ball is going up or down when it reaches the wall's position. The equation used to solve this problem is "change x=vot + 1/2at^2". The options for determining if the ball will go over the wall include determining the height of the ball when it reaches the wall's position (C), determining the speed of the ball when it reaches the wall's position (B), or both (E). The individual asking for clarification is unsure of the correct answer and is seeking further explanation.

Homework Statement



You are kicking a ball in the air that is sitting on the ground. You are told the initial velocity and the distance to a wall of a known height. To find out if the ball goes over the wall, you need to


A) determine if the ball is going up or down when it reaches the walls position

B)determine how fast the ball is going when it reaches the walls position

C)determine the height of the ball when it reaches the walls position

D)make sure the ball is at EXACTLY the height of the wall when it reaches the walls position

E)both a and b

Homework Equations


change x=vot + 1/2at^2


The Attempt at a Solution



I am not sure if the answer is C or E...I keep going back and forth... my reasoning is confusing me. Does anyone know? Thanks. Explanation is appreciated

What is your reasoning for choosing C? What is your reasoning for choosing E?
 

1. How do you determine if a ball goes over a wall?

To find out if a ball goes over a wall, you need to measure the height of the wall and the trajectory of the ball. This can be done using a measuring tape and tracking the path of the ball with high-speed cameras or specialized software.

2. Can you use any method to determine if a ball goes over a wall?

No, the method used to determine if a ball goes over a wall should be accurate and consistent. It is important to use proper measuring tools and techniques to ensure reliable results.

3. Are there any factors that can affect the accuracy of determining if a ball goes over a wall?

Yes, factors such as wind, air resistance, and the material of the wall can affect the trajectory of the ball and impact the accuracy of the measurement. These factors should be taken into consideration when conducting the experiment.

4. Why is it important to determine if a ball goes over a wall?

Determining if a ball goes over a wall is important for various reasons, such as in sports to determine if a goal or point has been scored, or in research to understand the physics behind projectile motion. It can also be used to assess the performance of athletes or equipment.

5. What are some potential applications of determining if a ball goes over a wall?

Aside from sports and research, determining if a ball goes over a wall can also be useful in engineering and construction to ensure the safety and effectiveness of structures such as fences, barriers, and walls. It can also be applied in gaming and virtual reality to enhance the realism of simulations.
