Hi everyone, i have been asked this question:

distance = s = ut + ½at²

u = initial velocity

a = acceleration

t = time

s = distance

what is the formula for the differential of s with respect to time (ds/dt) ?

(surely s/t is velocity, so the forumla is (u + at) But that can't be right because the whole paper is differentiation. so what do I REALLY have to do)

Please help, Les
