Homework Help: Physics

Posted by Aubrey on Sunday, October 3, 2010 at 2:36pm.

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
