Just before a field goal kick attempt at a football game, you use your knowledge of kinematics to predict by how much the football will clear the horizontal crossbar which is 3m from the ground. From the location of the football, you know the distance of the kick to be 35m. Assuming you estimate the angle of the kick is 45 degrees, and the initial speed is 20 m/s, determine the height of the ball at the location of the goal post.
