The diagram shows the velocity-time graph for a particle $P$ which travels on a straight line $AB$, where $vm{\text{ }}{s^{ - 1}}$ is the velocity of $P$ at time $t\,s$. The graph consists of five straight line segments. The particle starts from rest when $t = 0$ at a point $X$ on the line between $A$ and $B$ and moves towards $A$. The particle comes to rest at $A$ when $t = 2.5$.
a) Given that the distance $XA$ is $4{\text{ }}m$, find the greatest speed reached by…
