47.A man moves 10m in a direction of 37^(@) East of North then 5sqrt(2)m in South-East direction and finally 20m in a direction of 53^(@) South of West.Find the magnitude of resultant displacement of man?

A motor car A is travelling with a velocity of 20 m/s in the north-west direction and another motor car B is travelling with a velocity of 15 m/s in the north-east direction. The magnitude of relative velocity of B with respect to A is

A surveyor is surveying a cave. He follows a passage that goes 210 m straight west, then 90sqrt(2)m in a direction 45^(@) east of north, then 100 m at 37^(@) east of south. After a fourth unmeasured displacement he finds himself back where he started. determine the fourth displacement (magnitude and direction).

Wind is blowing in the east direction with a speed of 2m/s. A,. bird wishes to travel from tree A to tree B. Tree B is 100 m · away from A in a direction 37^(@) north of east the velocity of ·bird in still air is 4 m/s. ( a) Find the direction in which bird should fly so that it can reach from A to B directly. (b) Find the actual velocity of the bird during the flight. (c) Find the time taken by the bird to reach B.
