Expert Answer
I assume the question as follows

" If displacement of body is proportional to cube of time elapsed, then what is magnitude of acceleration ? "

---------------------------------------

displacement x(t) = k t3

where k is constant and t is time elapsed

velocity v = dx/dt = 3 k t2

acceleration a = d2x/dt2 = 6 k t
