Chapter 15.5, Problem 3eTH

Car P moves to the west with constant speed $v_0$ along a straight road, Car Q starts from rest at instant 1, and moves to the west with increasing speed. At instant 5, car Q has speed $w_0$ relative to the road $(w_0<v_o)$ . Instant 1−5 are separated by equal time intervals.
At instant 3, cars P and Q are adjacent to one another (i.e., they have the same position).

e. Complete the diagram at right by drawing car Q at its position at instants 1−5 as measured in the frame of car P.

Explain how your completed diagram is consistent with your velocity vectors from part d above.
