Show your work for further assistance.
You will not learn much physics by having others do your homework for you.
Start by calculating how long it takes the baseball to fall 2 meters. 
i can do the work all on my own but i'm not any good at the formulas, math is a very tough subject for me

Then you need a tutor. Math is the language of Physics. It will do you no good to copy our thinking.
