I thought the range depends on both the initial speed and the time of flight..

lol there are only 15 multiple chice sooo how did u manage to get 19/20? hahah

initial speed goes first i guess....

They both have the same height, that means they had the same time of flight.

oh ya haha 14/15

i still dont get it.. can u show it mathematically?
thx@!

think about it....u can jus eliminate c and d coz theyre always constant
since they are in the same height the time of flight is the same which leaves b as the only answer coz the velocity can influence how high or how far the ball goes
