The college physics department attached motion sensors to a football halfback. At one instant during the big game, the sensors indicated that the halfback's instantaneous motion was $-25 \text{ m/s}^{ 2 }$, and $+9 \text{ m/s} $.

Which of the following statements best describe his motion at this instant?

Note: The halfback wants to 'gain yardage', which means his goal is to move in the positive (+) direction.

A

He is gaining yardage while losing speed quickly (experiencing more than 1 'g').

B

He is losing yardage while losing speed at a moderate rate (experiencing less than 1'g').

C

He is gaining yardage while losing speed at a moderate rate (experiencing less than 1 'g').

D

He is gaining yardage, while gaining speed quickly (experiencing more than 1 'g').
