Vedclass · Answer

(b)
Displacement $=\frac{54 \sqrt{2}}{ Km }$
Distance $=2 	imes 54=108 \,Km$
Average speed $=\frac{108}{2}=54 \,Kmh ^{-1} 	imes \frac{5}{18}=15 \,ms ^{-1}$
Average velocity $=\frac{	ext { disp. }}{	ext { time }}=\frac{54 \sqrt{2}}{2} \Rightarrow 27 \sqrt{2} 	imes \frac{5}{18} \Rightarrow \frac{15}{\sqrt{2}} \,m / s$
