# Max Vertical Reach at Back Wall: Solving Projectile Problem

• xL0VEN0TE
In summary, the question is asking for the maximum vertical reach at the back wall, which should be approached as a peak height projectile problem, taking into account an initial standing reach. The equations d= vit+1/2at^2 and vf^2=vi^2+2ad can be used to solve the problem. The given information is a ball launched at 20 m/s at a 60 degree angle. The solution should include diagrams to illustrate the meaning of each variable, and use reasonable and unique values. Additionally, there should be a qualitative analysis of the differences between terrestrial and lunar jumping.

## Homework Statement

Finding the maximum vertical reach at the back wall.
This should be viewed as a peak height projectile problem (added to an
initial standing reach). Are diagrams
included to show the meaning of each variable? Are reasonable and unique
values used? Is the maximum vertical reach found? Is there a qualitative
analysis about the many dramatic differences between Terrestrial and Lunar jumping?

d= vit+1/2at^2

## The Attempt at a Solution

ball launched at 20 m/s. 60 degree angle.

Hi xL0VEN0TE! Welcome to PF!

What exactly is your question (and where is the wall)?

Anyway, show us what you've done, and where you're stuck, and then we'll know how to help.

Thanks. Sorry, I'm still kind of new to this website.
I just need to create a projectile problem with that info given.

## 1. What is "Max Vertical Reach at Back Wall"?

Max Vertical Reach at Back Wall refers to the maximum height a projectile can reach when launched at a specific angle and initial velocity, and the back wall acts as a boundary.

## 2. How do you solve a projectile problem?

To solve a projectile problem, you need to use the equations of motion, taking into consideration the initial velocity, angle of launch, and acceleration due to gravity. You can also use graphical or numerical methods to solve projectile problems.

## 3. What factors affect the max vertical reach of a projectile?

The max vertical reach of a projectile is affected by the initial velocity, angle of launch, air resistance, and the acceleration due to gravity. Other factors such as the shape and mass of the projectile can also have an impact.

## 4. Can you calculate the max vertical reach at any point in time during the projectile's motion?

Yes, the max vertical reach can be calculated at any point in time by using the equations of motion and the current position, velocity, and acceleration of the projectile.

## 5. How is the max vertical reach at back wall useful in real-world applications?

The max vertical reach at back wall is useful in real-world applications such as sports, engineering, and military operations. It can help determine the maximum height a projectile can reach and be used to optimize designs for maximum efficiency.
