14 feet is not a velocity.
It's a distance.

To catch a frisbee, a dog leaps into the air with an initial velocity of 14 feet.
Write a model for the height of the dog above the ground.
Model: h = (1/2)a*t^2+vot+ho where a = acceleration due to gravity; vo = initial velocity ; ho = initial height ; t = time in seconds
h = (1/2)(-32)t^2 + 14t + 0
h = -16t^2+14t

That depends on the height he reaches when he leaps.
Need to know value of "h"::
