I'm trying to figure out the average deceleration of an aircraft that touches the ground at 104 knots (175.53 ft/sec) and decelerates to zero in 3200 feet? Does anyone know how to do this? Thank you very much to all who reply.

Use the kinematic formula:
$$v^2 = 2 a \Delta x$$

Which gives you:
$$a = v^2/(2 \Delta x)$$
