The ball i throw is straight horizontal and the other i drop has V0 = 0 .

From what our physics teacher told us they should land at the same time. Is this statement correct ?

Does cofee really help the brain ? If yes how and in what proportions ? Secondary stuff i should know about ? And other things that could improve my memory and concentration power .

I can't focus from some time , my memory doesn't help me soo much . Is it because a bad nutrition , stress or even sex ? How should i gain back all my mind performance ? Do you have any suggestion what should i eat on what should i stop doing or anything ??

I have 17 years i am in highschool . I do want to apply to medicine . i had the max grades at biology i had big plans for it ..i haven't done my best .I had really big plans for it . But today i took a C.. the teacher was dissapointed ..i learnt the lesson but i just couldn't focus on it and i forgot it when she asked it from me . I have problem with concentration and memory but this day it was very bad . I need a plan to put myself on feet a scheldue .Now i feel down ..i feel soo weak and soo dissapointed of me what should i do ?

What requirements i need to enter there ? I am from other country (Europa) , i will finish in 2 years high school .
