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.
A pebble is dropped from the top of a 144-foot building. The height of the pebble h after t seconds is given by the equation h=−16t2+144 . How long after the pebble is dropped will it hit the ground?Interpretationa) Which variable represents the height of the pebble, and in what units?b) Which variable represents the time in the air, and in what units?c) What equation relates the height of the object to its time in the air?d) What type of equation is this?e) What are you asked to determine?

You use the ball of your foot.
Lineal foot can be measured on the ground. It is related to an actual measurement. Linear foot is a distance not necessarily measured along the ground. Also linear foot can refer to board feet.
6 feet
A foot fault is when you serve and your foot touches the ground on or or forward of the service line before you strike the ball.
yes.
In Netball, it is legal to move one foot only while you have the ball, this can only be the foot that was second on the ground after you gained possession of said ball.
Ball of the foot for sprinters and maratons
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.
By the Way, guys, this is based on the equation H= -16t2+vt+s
ball of foot means a ball has a foot stuck. to it so there is a diffrens beetween foot ball and ball foot. foot ball is a game with a ball. but ball of foot is when the foot is stuck to the ball! get it?
Not necessarily; you can bounce the ball off your foot, as long as your foot is on the ground, and it'll still be in play. If you kick it, though, it's a foul.
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.
Yes, as long as his or her foot is planted on the ground and does not move. There must be no "kicking" motion as it makes contact with the ball.
I believe this IS allowed in the NFL so long as the ball leaves the kicker's foot before crossing the line of scrimmage. I can't recall though ever seeing this type of kick DONE in an NFL game. ---- A field goal is attempted when the ball is placed on the ground for the kicker to kick or when the ball is dropped to the ground and kicked once it touches the ground and starts its bounce back up. In other words, the ball must have touched the ground or is touching the ground when the kick is attempted for the attempt to be considered a 'field goal attempt'. A punt occurs when a kicker kicks the ball before it has touched the ground. No points can be scored by a punt. So the answer to the question, as I understand it, is no. No. If a punted ball travels through the uprights, no points are scored. The ball has to make contact with the ground before it's kicked to score points, either by placekick or dropkick.
