no calculus, huh?
since
max value for occurs when
min ball speed will occur when it is at the peak of its trajectory ... when ... min speed would therefore be ... ?
max height occurs at
How did you figure all of these side details out like delta y = 0?
if the projectile starts on the ground and ends on the ground, what is ?
How do you determine which parts of the problem belong to X and which ones belong to y ?
I don't understand the question ... what parts do you mean?
For the last part can you at least show me the equations that I would use?
I gave you the equation for time to the top of the projectile's trajectory ... you need to calculate for that time.
you could also ignore the time element and use this equation to calculate ...
at the top of its trajectory,
