Question

Ronaldo approached the ball using a step-in kick with an average velocity of 80miles per hour. it has a low angle at approx. 30 degrees from the ground. Assume:

  1. the ball passes through the middle of the goal post
  2. player kicked the ball perpendicular to the goal post
  3. goal post dimension is 24ft x 8ft

 

Calculate:

  1. amount of time for the goalkeeper to react (sec)
  2. the velocity of the ball as it passes through the goalpost (m/s)
