physics question?

You would need the velocity (or speed) of the ball as it fell to answer this.

The equation is velocity= distance/time

And I'm not sure if this is correct, but you could try it.

Use 9.81 as the acceleration due to gravity and use the formula:

average acceleration = distance/(time)^2

x = 0.5 g t^2

you have the formula here

(http://en.wikipedia.org/wiki/Velocity)

g = 9.81 m / s^2 acceleration due to the gravity

first case x1 = 0.5 9.81 *0.46^2 = 1 m

t = sqrt (2 x / g)

x2 = 2.49 m

t2 = 0.71 s

x3 = 3.57 m

t3 = 0.85 s

x4 = 4.68 m

t4 = 0.97 s

x5 = 5.79 m

t5 = 1.08 s
