Question
Could you please tell me how to set this up and get thecorrect answer? I am confused! At time t=0 s, Ball A is thrown vertically upward with aninitial speed Vo for A. Ball B is thrown vertically upward shortlyafter ball A at time t. Ball B passes Ball A just as Ball A isreaching the top of its trajectory. What is the initial speed Vofor Ball B in terms of the given parameters? The accelartion due togravity is g. Thank you so much! Could you please tell me how to set this up and get thecorrect answer?

both reach the maximum height at the same time though theirstarting times are different.
time of ascent for ball A =T = Vo/g
time of flight for ball B=T-t=V1/g
when the initial speed of ball b is V1.
simplifying
Vo/g -t=V1/g
hence initial velocity of ball B =V1=Vo-gt
