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 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 : Form 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 velodcity vector of bus and man is `30^(@)+90^(@)=120^(@)`
