Problem
A scooter moves in two successive phases: first with uniform acceleration a1 for time t1 and then with a different uniform acceleration a2 for time t2. Which physical quantity for the whole journey is necessarily equal to the algebraic sum of its values for the individual phases?
(a) Average acceleration of the journey
(b) Final velocity attained at the end of the journey
(c) Total displacement of the journey
(d) Average speed of the journey
