1. The problem statement, all variables and given/known data
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?

2. Relevant equations
d= vit+1/2at^2

3. 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.
