Suppose you are a football player and you kick a ball for a field goal. Ignoring air resistance, the ball's horizontal velocity
A) changes throughout the path due to gravitational acceleration
B) is zero at the top of the path
C) is maximum at the top of the path
D) remains constant throughout the path

Question
