where do i differentiate??? pls hlp!

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

You just differentiate ut + ½at² with respect to t.

That gives u + at.


Why did the vector cross the road?
It wanted to be normal.
