Answer 1

Given information

Given attempted 36.0 m from the goalposts, whose crossbar is  above the ground.

To find: If the football is directed perfectly between the goalposts, will it pass over the bar and be a field goal? Show why or why not. If not, from what horizontal distance must this kick be made if it is to score?

Step-by-step explanation

Step 1.

From the example problem, the following values are given:

 

To know whether the ball goes into the goal post, the height of the ball at the moment it reaches the horizontal position of the posts must be compared with the height of the post. If the height of the ball is higher than that of the posts, then, the ball goes in.

To do this, the following general steps must be taken:

• list down the given values
• calculate the time taken by the ball to reach the posts
• calculate the height of the ball at this time
