A high school kicker makes a 34.0yd field goal attempt (in American football) and hits the crossbar at a height of 12.0ft.
1. What is the magnitude of the net displacement of the football from the time it leaves the ground until it hits the crossbar?
2. What is the direction of the net displacement of the football from the time it leaves the ground until it hits the crossbar?
3. Assuming the football took 2.70s to hit the crossbar, what was the magnitude of its average velocity?
4. What was the direction of its average velocity?
Describe why you cannot determine its average speed from these data.
