1. Figure 3.64 shows the position-time graphs of three cars A, B, and C. On the basis of the graphs, answer the following questions:i) Which car has the highest speed and which is the lowest?ii) ...
Solution
Velocity of car A = slope of x-t of A = 14-6/1.6 = 5km/hs
Velocity of car B = slope of x-t of B =14-0/1.4 = 10km/hs
Velocity of car C = slope of x-t of c = 14-2/1 =12km/hs
A) Car C has the highest speed and car A has the lowest.
B) There is no point where all three line intersect. so, all three car never meet at a same position.
C) When car A passes car C, car B is at 6km.
D) Time interval= 1.2-0.6 = 0.6hr
E) Relative velocity of Car C with respect to car A(vCA)=VC-VA=12-5 =7km/hr
F) R...
