If I throw a tennis ball straight up in the air at the same time my friend throws one straight down at the same height-initial height 3 feet and initial speed 2 km, which ball lands on the ground first, has the greater acceleration, lands with a greater speed, travels the farther distance and has the greater final displacement. Help-I'm totally lost-I don't where to start

  • Physics -

    both have the same acceleration,the one thrown down hits first, both have the same final velocity, the one up travels the further distance, both have the same displacement.

    Is this not true?
