1.	A man walks east with certain velocity. A car is travelling along a road which is 30^(@) West of North. While a bus is travelling in another road which is 60^(@)South of West. Find the angle between velocity vector of (a) man and car (b) car and bus ( c) bus and man.
Answer» Solution : From the diagram the angle between VELOCITY VECTOR of MAN and car is `90^(@)+30^(@)=120^(@)` The angle between velocity vector of car and bus is `60^(@)+60^(@)=120^(@)` The angle between velocity of bus and man is `30^(@)+90^(@)=120^(@)`
