Assuming that air resistance can be ignored,
s = ut + 0.5gt2
where
s is the distance travelled = 324 feet,
u is the initial velocity = 0 ft/sec,
t is the time (in seconds), and
g is the acceleration due to gravity = 32 ft/sec2
Therefore 324 = 0.5*16*t2 so that t2 = 20.25 and so t = 4.5 seconds.

Can you shoot with one foot on the base line in netball?
After you catch the ball, whichever foot touches the ground first is called your landing foot; if both feet touch the ground simultaneously, or if both feet are already on the ground when you catch the ball, then you can choose either foot to be the landing foot.Whichever foot is your landing foot, the other foot can be moved however you like, essentially so long as your landing foot stays in the same spot. Well, almost. To complicate things, you are allowed lift your landing foot off the ground, as long as your other foot remains still once the landing foot is lifted. You must also let go of the ball before your landing foot touches the ground again.Needless to say, you can't drag your landing foot, nor can you hop, skip or run with the ball. And you have to release the ball within three seconds.

The foot that you land on when you catch the ball is the foot you keep on the ground until the ball is released. the best idea is to jump as you catch the ball to avoid having both feet staying still.

Have your kicking foot a little ahead of the other foot when you receive the ball. As you are catching the ball, start your first step forward with your kicking foot and make the ball parallel to the ground turned to the inside just a bit. Then, step forward with your other foot and as it is landing on the ground, remove your opposite kicking foot's hand and raise it up(to keep balance). You should now be holding the ball with your hand that's on your kicking foot side, and then drop the ball straight down and meet the ball and follow your foot all the way through.
