For the ball to go straight into the goal, the kicker needs to be no more than 6.54 meters away from the goal.
For the ball to arc into the goal, the kicker needs to be between 58.5 and 65.1 meters away from the goal.
<h3>Explanation</h3>
How long does it take for the ball to reach the goal?
Let the distance between the kicker and the goal be meters.
Horizontal velocity of the ball will always be until it lands if there's no air resistance.
The ball will arrive at the goal in seconds after it leaves the kicker.
What will be the height of the ball when it reaches the goal?
Consider the equation
.
For this soccer ball:
- ,
- ,
- since the player kicks the ball "from ground level."
when the ball reaches the goal.
.
Solve this quadratic equation for , .
- meters when meters.
- or meters when meters.
In other words,
- For the ball to go straight into the goal, the kicker needs to be no more than 6.54 meters away from the goal.
- For the ball to arc into the goal, the kicker needs to be between 58.5 and 65.1 meters away from the goal.
Answer:
The correct answer would be A.
Explanation:
I have gotten this answer many times and have never failed once just trust me.
Answer: v =
Explanation: q = magnitude of electronic charge =
mass of an electronic charge =
V= potential difference = 4V
v = velocity of electron
by using the work- energy theorem which states that the kinetic energy of the the electron must equal the work done use in accelerating the electron.
kinetic energy = , potential energy = qV
hence,
Answer: the player pushing down on the floor
