# Question: A high school kicker makes a 30 0 yd field goal attempt

A high school kicker makes a 30.0-yd field goal attempt (in American football) and hits the crossbar at a height of 10.0 ft.

(a) What is the net displacement of the football from the time it leaves the ground until it hits the crossbar?

(b) Assuming the football took 2.50 s to hit the crossbar, what was its average velocity?

(c) Explain why you cannot determine its average speed from these data.
