Aplayer kicks a football from ground level with a velocity of 26.2m/s at an angle of 34.2° above the horizontal. how far back from a field goal (whose bar is at 4.0m) could the kicker be and still make a goal?

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.

Explanation

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.
