- A player kicks a football at the start of the game. After a 4 second flight, the ball touches the ground 50 m from the kicking tee. Assume air resistance is negligible and the take-off and landing height are the same (i.e., time to peak = time to fall = ½ total flight time). Calculate: Note: For each question draw a diagram to show the vector/s. Show all the step and provide units in the answers.
