Cole is standing on a level playing field when he throws a ball to Janice. The height, H, of the ball in feet above the ground t seconds after Cole throws the ball is given by the function.
H = 14 - (t - 3)2
What is the average number of feet the ball travels per second between t = 0 and t = 2 seconds?
(A) 1 foot per second
(B) 2 feet per second
(C) 4 feet per second
(D) 8 feet per second
