Answer:
i) acceleration from B to D is 0, because the velocity is constant (stays the same)
ii) whatever units of distathat might be, we can calculate the number:
for 4 time-steps (2 to 6) the velocity is 6 per time step, that makes 24 distance units in these 4 time steps. it's the same the area underneath the graph.
there is also the vertical line from 0 to 2. we can calculate that distance like the area of a triangle with 2*6 / 2 = 6
the total distance from 0 to D is therefore 30
Given data:
Yan speed;
Christopher speed;
Christophe starts 30 s later than Yan. Therefore, Christophe takes 30 s less than Yan to reach the same distance.
Part (A)
The distance is given as,
Let both Yan and Christophe meet at d distance from the start position. Therefore,
Substituting all known values,
Therefore, 600 s after Yan's departure Christophe will join him.
Part (B)
The distance is given as,
Substituting all known values,
Therefore, Christophe joins Yan after 6.17 km from the start.
