12 A particle moves in a straight line.

After the first 4 seconds of its motion, the displacement of the particle from its initial position is 0 metres.

One of the graphs below shows the velocity \(v\) m s−1 of the particle after time \(t\) seconds of its motion.

Identify the correct graph.

Tick (✓) one box. [1 mark]

Four velocity–time graphs for 0 ≤ t ≤ 4, each with a tick box: first, a straight line from v = 5 down to v = 0 at t = 4; second, from 0 up to 5 at t = 2 then down to −5 at t = 4; third, from 5 down to −5 at t = 2 then up to 5 at t = 4; fourth, from 5 down to 0 at t = 2 then up to 5 at t = 4
