http://members.shaw.ca/code/balls.JPG"

2. Relevant equations

I'm not sure what equations to use here, or even wether or not I need to use calc. Unfortunately we just started dynamics and most students don't know how to integrate yet (including me)

v = dx/dt

a = dv/dt = d^{2}x/dt^{2}= v dv/dx

Uniform rectilinear motion: x = x0 + vt

Uniformly accelerated rectilinear motion:

v = vo + at ; x = xo + vot + 1/2at^{2}; v^{2}= v^{2}o +2a(x-xo)

where o in all the above = initial.

3. The attempt at a solution

I don't even know where to start with this one. hence my question for help.

We know that a = 9.81m/s^{2}and also that every .5 second there is a ball dropped.

Do i have to integrate anything?
