A tractor travels in a straight line from a point $A$ to a point $B$. The velocity of the tractor is $vm{\text{ }}{s^{ - 1}}$ at time $t\,s$ after leaving $A$.
a) The diagram shows an approximate velocity-time graph for the motion of the tractor. The graph consists of two straight line segments. Use the graph to find an approximation for
(i) the distance $AB$,
(ii) the acceleration of the tractor for ${\text{0 \lt t \lt 400}}$ and for…
