A cannon is located on the edge of a cliff 100 m above a flat, sandy canyon floor. three cannon balls are launched from the cannon with the same initial speed of 50m/sec but at different angles. the cannon balls are identical except for their color. a red ball launched horizontally. white ball launched at 30degrees above horizontal. blue ball launched 60 degrees above horizontal.

If it were possible to launch all three cannon balls simultaneously, which order would they hit the ground?

i know you do not need to use quadratic equations for the mcat, but because i got the answer wrong i went ahead and did it anyway. i used the y = (vinitial)(t) + (1/2)(g)(t2) equation to solve for t. from the values of t that i got, i got that the red ball would strike the canyon floor at 4.5 seconds, the white ball would strike at around 2.7 seconds and the blue ball strike at 2.1 seconds. what am i doing wrong??
