Homework 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 = d2x/dt2 = v dv/dx
Uniform rectilinear motion: x = x0 + vt
Uniformly accelerated rectilinear motion:
v = vo + at ; x = xo + vot + 1/2at2; v2 = v2o +2a(x-xo)
where o in all the above = initial.
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/s2 and also that every .5 second there is a ball dropped.
Do i have to integrate anything?
