Q1 Write three equations of uniformly accelerated motion relating the initial velocity (u), final velocity (v), time (t), acceleration (a) and displacement (S).
Q2 Derive the following equations for a uniformly accelerated motion:
(i) v = u + at
(ii) S = ut + ½ at2
(iii) v 2 = u2 + 2as
where the symbols have their usual meanings.
