A man walks easr 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 man (c ) bus and man

Explanation

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 vector of bus and man is 30°+ 90° = 120°
